#756 How and Who am I - Right Now? and Now? and Now?

     It's critical to keep tabs on ourself - often. Why? Because we drift & get lost - a LOT!

     "… studies on attentiveness show that people are only briefly & unpredictably attentive. Attention habitually diverts to unrelated thoughts & feelings, leaving any task at hand to be managed 'on autopilot.' These studies suggest that mindlessness ('mind wandering,' 'zoning out,' 'task-unrelated thought') is 'one of the most ubiquitous & pervasive of all cognitive phenomena' and that it often occurs unintentionally, without awareness, occupies a substantial proportion of our day, and leads to failures in task performance." Lovas JG, Lovas DA, Lovas PM. Mindfulness and Professionalism in Dentistry. J Dent Educ 2008; 72(9): 998-1009.
     And that doesn't even mention wallowing & catastrophizing - our addiction to the re-runs of the never-ending-story-of-me!

     So, CHECK IN - often & regularly: 

1. Where am I physically - right here & now?
This is to actually "land" from thought-world, to reality. 

2. How am I feeling - Stressed or Peaceful?
If stressed, is this beneficial (functional) in any way, or just conditioning? If your current situation is more appropriately handled peacefully (almost always), can I accept & gently release stress with self-compassion?

3. Can I shift into Authenticity?
Of course you can, no question. As soon as you let go of being stress - not feeling or having stress, but stress-as-an-identity - you return to being authenticity. Authenticity - who you are & have always been - is still, silent, at peace, and spacious enough to hold any & all of life's challenges, including your young frightened part ("poor,  hurt, needy me"), with unshakable equanimity & grace.
     This young part is a very small, temporary part, that reflects the effects of traumas & conditioning. It's nowhere near your actual identity, which is inconceivably vast. Don't take your young part so personally, so seriously! Hold it lovingly BUT lightly. Your authenticity is vast, fluid & completely untouched by life's inevitable ups & downs: gain & loss, status & disgrace, censure & praise, pleasure & pain. 
     Your authenticity can be compared to a wise, loving, nurturing grandparent or wise elder. Your young part can be compared to a three-year-old grandchild. The two have vastly different depths, scopes & capacities.  
     Who you really are is spacious enough to easily hold your young, beat-up part in safety & unconditional love. BE authenticity.

     “Inner peace doesn't come from getting what we want, but from remembering who we are.” Marianne Williamson

 

#747 Bare Awareness of Difficult Stuff

     “I invite you to sit with the anger and frustration – not in judgment, not with the intent to change or do anything with it, but just with bare awareness of it. Often, that helps reveal a previously undisclosed feeling or issue that is manifesting as anger or frustration. It is a lot easier to address the root issue than its manifestation. Often merely seeing what is underneath the anger and frustration helps dissipate it.”

      Susan J. Stabile, Lion’s Roar, November 2017.

#716 How Mindfulness (MBSR) Can Change Your Life

     "Mindfulness is a way of being - a basic human quality of awareness that is cultivated by learning to pay wise attention to whatever is happening in our lives.
     People who participate in a mindfulness-based stress reduction (MBSR) program, learn through their own experience how to take better care of themselves, by understanding the interplay of mind and body, allowing for greater access to inner resources for coping, growing and healing. 
     MBSR is an approach that combines meditation, dialogue, reflective inquiry, mindful yoga and movement, as means to assisting participants to work more effectively with stress, pain and illness, as well as the challenges of life in the 21st century."

 

#692 Mindfulness Training & Wisdom

     Participants in mindfulness training programs eg 8-week MBSR courses, often come to better manage their stresses, & thus improve the quality of their lives. However, these objectives ultimately require nothing less than the cultivation of wisdom - which mindfulness practices facilitate.

     "Although wisdom is a complex concept and difficult to define, historically it has been considered the pinnacle of human development.
     (Bergsma & Ardelt) define and operationalize wisdom as an integration of cognitive, reflective, and compassionate personality characteristics.

     (They) define and operationalize wisdom as a three-dimensional personality characteristic: 
          • the cognitive dimension of wisdom refers to the desire to know the truth. This does not only imply a knowledge of facts but also a deep understanding of life, particularly with regard to intrapersonal and interpersonal matters, including knowledge and acceptance of the positive and negative aspects of human nature, of the inherent limits of knowledge, and of life’s unpredictability and uncertainties.
          • A deep and undistorted comprehension of reality can only be achieved by overcoming one’s subjectivity and projections through the practice of (self-)reflection. The reflective dimension of wisdom highlights this aspect and represents the ability and willingness to invest in self-examination, self-awareness and self-insight. It requires the perception of phenomena and events from different perspectives and the ability to ‘see through illusions’. ... ‘one must be able to first become aware of and then transcend one’s projections before one can develop both the empathic skills and the cognitive processes associated with wisdom’.
          • Reflectivity tends to reduce self-centeredness, which leads to a deeper understanding of one’s own and others’ motives and behavior, and is likely to result in greater sympathetic and compassionate love for others. All-encompassing sympathetic and compassionate love accompanied by a motivation to foster the well-being of all denotes the compassionate component of wisdom.

     ... this definition of wisdom does not imply that wise individuals will avoid or suppress negative emotions toward themselves or others if they arise. On the contrary, through self-awareness and self-examination (the reflective wisdom dimension) wise persons are able to acknowledge, regulate, and ultimately overcome their negative emotions and projections without adversely affecting their own lives and that of others. For example, the practice of mindfulness and mindfulness meditation appear to facilitate the acceptance and eventual transcendence of negative emotions and behavior."

#593 Naturally

     While stuck in the muck of the ego - the small, tight, scared, anxious, fearful, angry, sad, time-poor, jangled, self-talk-filled, tiresome, stressful, painful old nightmare - the idea of embodying qualities like clarity, peace, silence, timelessness, stillness, kindness, lightness and effortlessness, may sound like a frustratingly impossible list of "shoulds".
     But it's neither externally imposed, nor a far-off, hard-to-reach destination. It's right here, right now, always, effortlessly available, to all of us. Just remember the direct experience - how you feel while:
                    • hugging a beloved human or other living being; 
                    • wordlessly awed in Nature;
                    • selflessly bringing healing to another.

     This is the freely flowing process of NATURAL human life. Just keep remembering & come back to reality, gently, kindly, peacefully, seamlessly, with timeless patience, as soon as you feel the muck of the ego. THIS WAY of returning, IS having returned already.

#580 "All Manner of Things SHALL be Well" ??

Old echoes may ache,
Doubts inherited can pummel,
Reflexive unskilled tendencies can simmer,
AND YET - "all manner of things ARE well" - NOW

For deep within & all about ...
Profound wisdom,
The vigilance of the most loving grandparent,

Immediately, effortlessly ever-present ...
Spacious clear AWARENESS -
Silent, still, timeless, loving, peaceful, joyful,
Embracing EVERYTHING.

#577 Awareness or "Ordinary Mind" - Choosing Wisely

     Mindfulness training reduces stress by letting us function at a higher level of consciousness.
     Our "ordinary mind", is very useful when assigned certain specific tasks eg solve a math problem. But let loose, it tends to grind out an awful lot of unhelpful, to agonizingly disruptive material (wallowing, catastrophizing, daydreaming, anxiety, confusion).
     Awareness, on the other hand, is marked by clarity, silence, stillness, peace, timelessness, kindness, and joy. Note the absence of struggle, stress and suffering. This level of consciousness is our birthright as human beings - homo sapiens sapiens. Over thousands of years, we've been gradually evolving to inhabit this level of consciousness with increasing stability. Mindfulness practices are designed to help us get there in THIS lifetime.
     We're so conditioned to identifying with (instead of simply using) "ordinary mind", that it's our default mode of consciousness AND way of being. Stressed out, struggling, inefficient is how we see ourselves! Even while taking an 8-week Mindfulness course, some participants drop out when their academic / work stresses rise! These folks trust ordinary mind when what they need is the more efficient, more effective, stress-free, higher level of consciousness. This, like other aspects of our conditioning, needs to be deeply examined and questioned. See: http://mindfulnessforeveryone.blogspot.ca/2014/10/576-practicality-of-prioritizing-quality.html

     Very closely related to trusting the old grit your teeth & grunt approach to work over a more mindful approach, is ignoring self-care and trusting that putting everything directly into one's work is the answer (to what ?). See: http://healthyhealers.blogspot.ca/2014/10/quality-of-life-for-one-for-all.html

     A funny, yet very serious aspect of "trust" to examine deeply, in one's own life: http://mindfulnessforeveryone.blogspot.ca/2014/02/492-mindfulness-practice-real-world.html

#576 Practicality of Prioritizing Quality

     When we compare a homeless alcoholic guzzling the handiest liquid intoxicant (including mouthwash, hair tonic, etc), with a sophisticated wine connoisseur, we tend to identify with the latter. 
     For one, it's all about becoming intoxicated as quickly as possible - mindlessly escaping reality.
     For the other, it's all about quality, with little or no intoxication - consciously savouring reality.

     All of us can be connoisseurs of our own life! We can carefully monitor the quality of our current thoughts, speech, and behaviours for lasting, timeless quality by asking:
          • Do these lead to stress and suffering, or to the end of stress and suffering?
          • If these lead to stress, are they necessary?
          • If not necessary, why do these again?
          • If these lead to the end of stress, how can I master these as skills?                                           Thanissaro Bhikkhu

#566 Mindfulness Meditation - Expectations & Realities

     Most of us are drawn to meditation practice because we realize that we're anxious, stressed out, depressed. We want all that mess to go away so we can be happy. We hope to use this technique like a scalpel to excise the irritants from our lives.
     But, meditation practice does not work like that. In fact, we'll actually see reality with increasing clarity. Like anything else in life, when we lack the skills to deal with a situation eg skiing down a black diamond slope, we're scared & very reasonably, highly resistant. However, with expert instruction & practice, we gradually look forward to & actually enjoy black diamond runs. 
     Likewise, quality meditation instruction & life-long practice helps us develop skills to negotiate all the slopes of life, from bunny hills to back-country trails, with awareness, kindness & joy.

#550 Mindfulness - State or Trait?

     "Passing states like joy, fear, excitement, or depression come and go like the weather. But enduring traits, like reliability or empathy or natural mindfulness, are more stable, and thus more dependable from moment to moment. Certain qualities can take the form of a state or a trait. Consider happiness, for example. Positive experiences might make you happy for an hour or a day, but as soon as the state passes, the feeling fades as well. By contrast, the trait of happiness, the enduring sense of subjective well-being, doesn’t come and go but abides as the backdrop and flavor of all your experiences. 
     Meditation that just induces a pleasant emotional or mental state for as long as you’re practicing, a state that then fades when you stand up and go about your day, has only limited value in the stress and strain of ordinary life. The purpose of mindfulness meditation is to cultivate & strengthen the TRAIT of mindfulness — enhanced present moment awareness — so you can extend it to every situation you encounter, no matter how challenging, and reap the ongoing benefits.
     ... The results of (this) study suggest that mindfulness intervenes in several ways in the usual stress cycle: by helping with the regulation of negative emotions that tend to intensify stress and by enhancing restful sleep, which in turn tends to moderate stress. ... Of course, for those of us who don’t score high on natural mindfulness, there’s always the practice of mindfulness meditation!"                     Stephan Bodian

#514 Surviving - OR - Thriving in your Studies?

     It's well known that most of our stresses today, are misinterpretations of threats to our egos, as if these were threats to our actual lives. Extreme examples: one man looks at another man, or another man's girlfriend, "the wrong way", causing (at times lethal) confrontation; paralyzing anxiety over writing "high-stakes exams" eg fellowship, board or bar exams; cyber-bullying tragically leading, in some cases, to suicide. We routinely take some things way too seriously; while at the same time, we pay too little attention to things that actually matter. How we direct our attention & energy can make the difference between barely surviving & thriving.
     For students it's very important to realize that excessive stress also negatively impacts judgment & memory. While studying, if you're worried about doing badly in a subject, you likely waste huge amounts of time & energy listening to negative self-talk. Stress also interferes with your ability to remember the material, so the efficiency of your studying is greatly reduced. Then, while writing the exam, if you're stressed, your judgments eg choices you make on a multiple-choice exam, are negatively impacted. See: http://mindfulnessforeveryone.blogspot.ca/2014/02/490-safe-learning-environment.html
     Not well known is the fact that the opposite of fear-based stress is love. See: http://mindfulnessforeveryone.blogspot.ca/2012/06/140-love.html How much effort did it take for you to learn all sorts of information about your favorite sport or hobby? None - it certainly didn't feel like work! How difficult is it for you to remember all this info? Easy, effortless! 
     To the extent you're able to bring about liking or even loving the subject that you're studying, you eliminate all the self-defeating, energy-draining barriers that keeps the information from going deep into your memory banks. If you don't find the subject itself inherently likeable, can you see how much good will come from knowing it? Now, what you study, will behave EXACTLY like all that information about your favorite sport or hobby. You are learning to open up, & welcome in information. Once it's deeply within "the marrow of your bones", it's readily retrievable & appropriately applicable in any context (test or real-world eg clinical application).
     Learn to become aware of self-talk, thoughts & moods. If they're not helpful, learn to let them go & switch over to ones that work for you! YES YOU CAN!

#499 What is there to Accept?

     "Growing up" is an interesting process. A wise parent introduces new experiences to her child very gradually, so that these changes stimulate healthy growth & maturation. We know that exposure to too much, too early, results not in healthy maturation but counterproductive stress.
     However, our maturation process extends far past the time we leave home - it truly is "lifelong learning". So we ourselves must, consciously & unconsciously, become our own gatekeepers - ideally titrating new material at a pace we find growth-stimulating. Unfortunately, some of us can't say no, taking on way more than we can handle well; while others get stuck in the opposite rut - living very small, boring, unchallenging lives. What we assume we can't handle well, we consciously & unconsciously avoid, delay, suppress, oppose etc.
     Through mindfulness training, one of the many things we become increasingly consciously aware of, and learn to accept, is our current gatekeeper role, how it affects our life, and the fact that the actual quality of our life is literally in our hands.
     Then, upon becoming aware of models & roadmaps of normal psychosocial development (evolution of consciousness, or maturation), we realize that human potential is literally beyond anything we can currently imagine. We become & remain aware of, & accept the fact, that we're up in the air, sitting alone at the controls, flying our own personal helicopter called "this life" to destinations we've never experienced before. This is both amazing & daunting. We're called to be our own personal highly-skilled gatekeepers, sports psychologists, & life coaches.

#495 Is the Devil in the Details?

     A few years ago, during a break in a continuing medical education course, I overheard a group of young female physicians chatting about their children. One comment stuck: "I just hope they don't grow up to be assholes!"
     Isn't that our hope for ourselves as well? And yet, much of our lives are spent reacting to minor details - "sweating the small stuff", making a big deal out of them, then recuperating by zoning out with mindless distractions, booze, sleep etc. Our life too easily gets pilfered away, lost in details.
     Of course there's nothing wrong with the details themselves, the waste is in the sour attitude of "putting out fires": http://mindfulnessforeveryone.blogspot.ca/2014/02/493-how-we-fail-to-prioritize.html Such an attitude assumes that we're constantly battling annoyences. NO - we're actually LIVING, & CHOOSING the QUALITY of our LIFE. Our problem is settling for the wrong attitude. A wise person once said: "Every day is a good day." Statements like this really irritate some people - where's the locus of control?

#493 How We Prioritize - Why We Fail to "Pick our Battles"

     How do we know when we have to drop everything, & immediately redirect all our resources to a new specific issue? A classic example: we suddenly feel searing pain (anywhere in the body-mind) - all our alarm bells go off at once - a massive call for action & we're instantly in full fight-freeze-flight mode. We're running on emotions, everything else - including ability to make mature judgments - shuts down. This is the default mode for most people in life-or-death emergencies - instinctively prioritized reaction to the threat to our survival.
     Unfortunately, few of us appropriately distinguish acute life-or-death emergencies from minor threats: to our ego, comfort & convenience. Because of this common conflation, stress, anxiety & depression are epidemic & becoming increasingly incapacitating.
     So the problem is that our firefighters routinely break down the doors & windows, whisking us off to the ER, even though most of the time, there's no fire - just kitty stuck in the tree. This biological version of "the boy who cried wolf" is very hard on everyone concerned - internal friction: http://mindfulnessforeveryone.blogspot.ca/2013/10/423-what-is-this.html and http://www.johnlovas.com/search?q=fight

#490 A Safe Learning Environment

     We now appreciate the need to feel safe to be able to learn as well as to behave like civilized mature members of society.
     Stress impedes both learning, and the ability to make mature judgments. However, learning is inherently stressful in so far as the student (& we're ALL students) is never quite sure about what's going on - uncertainty, ambiguity, liminality is uncomfortable yet omnipresent - learning always comes with "growing pains"! 
     But as a society, we have a largely unexamined, yet very powerful aversion to discomfort. This learning / discomfort combo often results in emotional reactions. Teachers / instructors / professors & students blame each other for the discomfort.
     Of course teachers / instructors / professors also experience stress & its negative effects. They often care deeply for the material they teach, and may resent a perceived lower level of interest on the part of students. Teachers' memory of themselves as students tends to become idealized over the years. Teachers are also aware that course evaluations are important to their career and that students whom they discipline or give low marks to, will likely retaliate with harsh course evaluations. So teachers may also, at times - also out of fear / stress - react inappropriately to students. Such behaviour, though caused by fear, tends to be interpreted as "bullying" because of the power differential. Most bullying is probably at least partially fear-based.
     Students & teachers - everyone - can & needs to cultivate alliances rather than adversarial relationships. Individuals must clearly recognize when they're stressed. Self-awareness is critical, since one cannot care properly for another human being, as called for by an alliance, while one is afraid, angry & stressed out. A warm caring attitude cannot be faked nor mandated. It can only happen when fear & anger are gone. It's a shared responsibility, among individuals & groups, to cultivate caring, civilized environments fit for quality human life.
     Stress impairs judgment. Recognize & let go of fear & anger BEFORE you say (email, text) or do anything. This requires mindfulness practice, making mistakes, accepting rather than denying the mistakes, more mindfulness practice, making fewer & smaller mistakes, accepting rather than denying the mistakes, more mindfulness practice, making fewer & smaller mistakes, ... on & on for life!
     By becoming increasingly mindful, we cultivate a safe learning environment for ourselves & others.

#487 Mindfulness, Science & Reductionism

     The latest mindfulness-based intervention, "Mindfulness-Oriented Recovery Enhancement (MORE), is designed to train people to respond differently to pain, stress & opioid-related cues."

     The definitions provided in the paper (below) of mindfulness, reappraisal & savoring are so brief as to be misleading. Clearly there's MUCH more to mindfulness than awareness for the purpose of self-regulation. Reappraisal / reframing, at least as it pertains to mindfulness, is also MUCH more complex, including acceptance and seeing things clearly as part of the overall big picture. Similarly, savoring as defined below sounds simplistic - FAR less nuanced & balanced than one experiences through mindfulness meditation practice. But such is the nature of reductionism, an inherent part of science.

     "MORE targets the underlying processes involved in chronic pain & opioid misuse by combining three therapeutic components: mindfulness training, reappraisal & savoring.
     • Mindfulness involves training the mind to increase awareness, gain control over one's attention & regulate automatic habits.
     • Reappraisal is the process of reframing the meaning of a stressful or adverse event in such a way as to see it as purposeful or growth promoting.
     • Savoring is the process of learning to focus attention on positive events to increase one's sensitivity to naturally rewarding experiences, such as enjoying a beautiful nature scene or experiencing a sense of connection with a loved one."

#414 Mindfulness is Mainstream

     88% of American college students who responded to the 2013 National College Health Assessment survey said they felt overwhelmed by everything that they had to do, and 49% said they felt that things were hopeless. And these 'emerging adults' have yet to face the real responsibilities and challenges of adult life!
     Life is moving faster, it's more complicated, more interconnected, less controllable and experienced as far more stressful than ever before. And we have fewer traditional resources to help us cope and promote resilience (extended families with stay-at-home Mom, stable small town communities, community of faith, etc). More about the significance of "community": http://www.johnlovas.com/2013/10/what-really-matters-in-community.html

     Mindfulness practices are helping to fill this critical void in our private lives, health-care, education, law, the arts, management, government, and now the military:
     "The U.S. Marine Corps, known for turning out some of the military's toughest warriors, is studying how to make its troops even tougher through meditative practices, yoga-type stretching and exercises based on mindfulness.
     Marine Corps officials say they will build a curriculum that would integrate mindfulness-based techniques into their training if they see positive results from a pilot project. Mindfulness ... emphasizes active attention on the moment to keep the mind in the present. 
     Facing a record suicide rate and thousands of veterans seeking treatment for post-traumatic stress, the military has been searching for ways to reduce strains on service members burdened with more than a decade of fighting in Iraq and Afghanistan. 
     Marine Corps officials are testing a series of brain calming exercises called "Mindfulness-Based Mind Fitness Training" that they believe could enhance the performance of troops, who are under mounting pressures from long deployments and looming budget cuts expected to slim down forces."

#398 Clarity of Mind - the Jar of Soil & Water Metaphor

     If we take a glass jar, add some soil, fill it with water, put a lid on, then shake it all up, we've created a cloudy suspension of particles - dilute mud. Now if we leave this jar undisturbed, we see that inevitably all the soil particles gradually settle to the bottom, leaving crystal clear water above. 
     The soil particles represent the myriad things to which we attend. The more "going on in our lives", the more darkly turbid the jar contents. Inherently pure clear water represents our mind.
     The more we practice mindfulness meditation, the more opportunity we provide for the jar to sit still, the more particles settle, and the greater the clarity of the water.
     Each time we notice that we're thinking, worrying, daydreaming etc - playing or wrestling with soil particles - we patiently gently effortlessly - without shaking the jar - let it go, returning our awareness to the physical feel of the present moment eg breathing, posture, muscle tone, sounds.
     Although most of us only have rare, very brief experiences of our jar containing crystal clear water (all mud at the bottom), we all have this natural capacity. It truly is simply (though not easily) a matter of prioritizing time for this evolved activity. We have a lifelong habit of playing & struggling with mud. Now we know how to intentionally achieve clarity of mind. Far more exciting than theory - just another floating particle - is seizing the opportunity now to actualize & stabilize this clarity.
