What is consciousness? Comatose are aware

Sam Jones, Washington Post, 11/2023; Pat Macpherson, Dhr. Seven (eds.), Wisdom Quarterly

Trapped in a body that's out of its mind.
Some brain injury patients may appear to be in a coma, but they are not. They are processing at least some of what is happening around them but cannot physically respond.

Without a physical response, a physician might assume that a patient hasn’t understood, said Dr. Sudhin Shah, a neuroscientist at Weill Cornell Medicine in New York City. Referring to the patient, she said, “Unfortunately, it could be that you were processing, you were understanding, you were wanting to talk to me. You just can’t.” More: Some coma patients may be conscious. and new research could identify them.

Neuroscience of Awakening: Buddhist Brain

Asangoham, April 29, 2023; Eds., Wisdom Quarterly

The Neuroscience of Awakening: Your Brain on Buddhism
(Asangoham) Our brains have the amazing ability to change themselves. This is called neuroplasticity.

[The brain is not the mind. Mind is near the heart]
Our brains are not fixed structures. Rather, they are dynamic systems that are constantly changing and evolving in response to the environment.

In fact, research done in the last decade has shown that the brain is much more malleable and responsive to change than previously thought.

Neuroplasticity can occur at different levels of the brain, from the level of individual neurons to the level of entire brain regions.

One of the primary features of neuroplasticity is that it is activity-dependent. This means that the changes in the brain are driven by experiences and activities.

For example, if a person engages in a particular activity repeatedly, such as learning to play a musical instrument or practicing a new language, the brain will adapt to these experiences and develop new neural connections that support these activities.

Neuroplasticity also has important implications for understanding the relationship between the mind and the brain. If the brain can change and adapt in response to experiences, this means that our minds also can change and adapt.

But what do we mean when we say “mind”? What is a mind? The mind is nothing but thoughts. There is no mind without thoughts.
  • [There is. Mind knows. Thought is the attempt to symbolize conceptualizations. According to the Abhidharma and verifiable personal experience, there were all these things before the brain. They exist independently.]
Therefore, because of the neuroplasticity of brains, we can radically change our thought patterns, or our minds. We can change our thought patterns to have happier or more beneficial minds.

But even more than this. We can also develop the capacity to slow or even stop thought completely by the activity of focusing attention on the emptiness or empty silence between thoughts.

Many religious and mystical traditions, including many schools of Buddhism, teach that it is this capacity to rest in the emptiness between thought that ultimately reveals the very nature of reality, and the reality of who we truly are.

Can we change a deed? (Karma and its Fruit)

Ven. Nyanaponika Thera aka Seigmund Feniger (Kamma and its Fruit via accesstoinsight.org, BuddhaNet edition, 1996) edited by Dhr. Seven, Ashley Wells, Wisdom Quarterly 2020 

The causes are our deeds.
The Buddha taught: "If one says that in whatever way a person performs a karmic deed [an intentional action], in that very same way one will experience the result (vipaka, phala) -- in that case there is no [possibility for a successful] spiritual life and no opportunity would ever appear for the complete ending of all suffering [enlightenment and nirvana].

"But if one says that a person who performs a karmic deed [that bears results] that are variably experienceable [that is to say that ripen differently] will reap that deed's results accordingly -- in that case there is [the possibility for a successful] spiritual life and an opportunity for making a complete end of all suffering" (AN 3.110).

I.
Most writings on the doctrine of karma emphasize the strict lawfulness governing karmic actions and results, ensuring a close and clear correspondence between deeds and their fruits.

While this emphasis is good enough, there is another side to the complex working of karma, a very important side that is rarely noted. This is the modifiability of karma.

The fact is that the lawfulness (regularity, predictability) that governs the working out of karma does NOT operate with mechanical rigidity like the "laws" of physics are said to behave. It allows for a considerably wide range of modifications in the ripening of the fruit.

If karmic action were always to bear fruit invariably in the same way and with the same magnitude, and if modification or annulment of karmic results were excluded, liberation (moksha) from the cycle of suffering (samsara) would be impossible. Why?

An inexhaustible past amount of unwholesome karma would always throw up new obstructive results (mental resultants and fruits). So the Buddha taught:

"If one says that a person who performs a karmic action [deeds that have the power to produce a distant result] that can be experienced in a variety of ways will reap the results of that deed accordingly — in that case there will be [a good purpose for leading this] spiritual life [taught by the Buddha as a means of waking up and] making a complete end of suffering" (AN 3.110).

Like any event in physics, the mental process constituting a karmic action never exists in isolation. It always exists in a field. So its efficacy (the power to produce its results) depends on its own potential AND variable factors of its field. These things can modify the results of an action (a karmic deed) in numerous ways.

Hey, that means there's hope! We can be free!!
For example, we see that a particular karma (an intentional physical, verbal, or mental act), either whether it's skillful or unskillful (good or bad) may sometimes have its result strengthened by "supportive karma," or weakened by "counteractive karma," or even annulled by "destructive karma."

The occurrence of the results can also be delayed if the coming together of outer circumstances required for the ripening of a deed are not complete. That delay may then provide a chance for counteractive or destructive karma to operate.

[In other words, there is hope no matter what we have done or are doing. We can turn it around and progress to a "successful" spiritual life crowned with awakening/enlightenment and nirvana, which is the end of all suffering. This is what the Buddha taught when he talked about the hopelessly complex teaching of karma and karmic results.] More

Psychology: "mindfulness" in science (audio)

Amber Larson, Dhr. Seven, CC Liu, Crystal Quintero, Wisdom Quarterly; Ven. Nyanatiloka; Professor Ellen Langer (Harvard/ellenlanger.com), Krista Tippett (onbeing.org, 5-29-14)
What could Sid or the Buddha teach Ziggy Freud on the psychotherapeutic couch?
Note the Buddha heads behind Dr. Freud's chair. This is the original therapy couch (HW)
Langer says keep it simple; notice things rather than practicing mindlessness (Kris Krug)
 
Science of Mindlessness and Mindfulness
Counter Clockwise
Harvard University social psychologist Prof. Ellen Langer's unconventional studies have long suggested what brain science is now revealing: 

Our "experiences" are formed by the words and ideas we attach to them, that is, the labels we add to our cognitions. Naming something "play" rather than "work" can mean the difference between delight and drudgery. 

She is one of the early pioneers -- along with figures like Buddhist researcher Jon Kabat-Zinn and Herbert Benson -- drawing a connection between mindlessness and unhappiness and between mindfulness and health. 

Going deeper
"Mind" (citta) is a process, not a thing.
Buddhism is not mere material "science" (the particle physics the Buddha talked about in terms of kalapas) but goes beyond materiality to mental- and mystical-experience, detailing processes that science has yet to acknowledge, detail, or come anywhere near explaining.
 
The Buddha meant two distinct practices, mindfulness/clarity (sati-sampajañña) -- present time awareness that does not reach back into the past or project forward into the future -- and the fourfold setting up of mindfulness (satipatthana/vipassana) as a formal meditation practice that, on top of absorption, leads to insight and liberation of mind and heart.
 
Buddha's Brain (Dr. Rick Hanson)
Dr. Langer describes just the initial practice of "mindfulness," bare awareness, which is possible without formal meditation or yoga.

She recommends the basic practice of “the simple act of actively noticing things.”
 
This is bare awareness, which in a Buddhist context is practiced as "presence of mind" in the absence of the internal distractions that come from discursive elaboration (thinking about), mental proliferation (papañca), and interpretation/color-commenting based on our mental formations and fabrications (sankharas).
Psychologists distinguish "top-down processing" (projecting, seeing what one thinks is there, going from the mind to the outside world) from "bottom-up processing" (going from what's actually there to the mind that perceives it and attempts to understand it free of prejudice).

What is "mind"?
This gray material goo is not "mind."
MIND in Buddhism can refer to consciousness (viññāṇa), knowing (ñāna, one of the "psychic powers" or iddhis, a synonym of wisdom/paññā, the best and hightest being aññā), discrete mental processes (cittas), the "mind door" near the heart, perception (saññā), the ~50 mental formations (sankharas) led by volition/will (which is the basis of karma), or more comprehensively as the Four Aggregates (Sanskrit skandhas, Pali khandhas) apart from the first, namely, form or materiality (rūpa).

Karma O Karma! (action)

Ashin Narada (Sitagu Int'l Buddhist Academy), Dhr. Seven, Amber Larson, Wisdom Quarterly
Karma Man to the rescue by cartoonist-comedian Dan Piraro (bizarro.com)
 
“All beings have karma as their own, as their companion, as their inheritance.”

Karma is the law of causation in a moral (sila, virtuous, ethical) sphere. Rebirth is its corollary.  
 
Karma and rebirth are fundamental and interrelated teachings in Buddhism.

These two doctrines existed, mostly kept from the public, in India prior to the Buddha. But it was the Buddha who formulated and explained them in the manner we have today. Seers (rishis) clearly knew of them from their own meditative attainments, but what they made of, what they deduced and concluded

What is the cause of the inequality that exists among people?  How do we account for the unevenness in this ill-balanced world?

"Karma Man" (i.imgur.com)
WHY, WHY, WHY ME? Why is one born into luxury, endowed with excellent mental, moral, and physical qualities, and another raised in poverty and abject misery? Why should one be born a millionaire, another a pauper? Why is one a prodigy, another an dimwit? Why is one born with virtuous characteristics and another with criminal tendencies? Why are some artists, mathematicians, linguists, and musicians from the cradle while others toil congenitally blind, deformed, or inept? Why are some blessed and others cursed from birth?
 
The ripening of karma is, of course, not the only reason why things happen. But it is constantly there sustaining and modifying conditions. We may be helped or harmed by others, pulled from misery or thrown into it unfairly. ("Fairness" plays in both directions, though we rarely complain aloud about our unearned gains and advantages, and we bask in the pity and sympathy others may bestow on us in our presumed helplessness and how "unfairly" we are being treated by the world as if everyone were born equal in merit and opportunity).

Either there is a definite cause for this inequality or there is not.  If there is not, the inequality is accidental.

Good sense precludes us from attributing this inequality to blind chance or chaotic accident.  Rather one senses that in this world nothing happens to anyone who does not for some unknown or unclear reason or other deserve it.
 
But "deserve" is a troublesome word, connoting that the universe or society or others are trying to "teach" us something, when it is simply the impersonal working out of actions attracting their consequences and/or us meeting ourselves again and again. We may be trying to teach ourselves something, but the impersonal world without is simply going along as it wishes. To impute a purpose or plan out there is dangerous and misleading. To see one in here may be helpful and may accord with pre-birth agreements or plans to undergo types of experience in one or more lives.

Our lives are shaped by our intentions/volitions rooted in benefit (nongreed, nonhatred, nondelusion) or harm (greed, hatred, delusion). When our hearts/minds are purified of these harmful elements, joy follows us like a dependable shadow.
 
Usually the actual reason or reasons why things happen cannot be comprehended by ordinary intellects. The definite invisible cause or causes-and-conditions of the visible effect may not be confined to the present life. What is happening to "us" is not happening because of who we are but rather who we have been, often very-very long ago. A cause may be traced to a proximate or remote past birth. With the aid of past life regression, hypnosis, telesthesia, and retro-cognitive knowledge, it may be possible for a highly developed seer to perceive events that are ordinarily imperceptible to the physical eye. Buddhists speak of such a possibility.

The majority of people ordinarily attribute inequality to a single cause such as the will of an all-powerful creator being, gods (devas) at play, or Fate. In place of the whim of an almighty being (an uncaused cause), or the caprice of the universe, the Buddha explained the impersonal law of karma as the cause of many significant events.

How do modern scientists account for the inequality among people? Confining themselves to sensory data, they attribute inequality to heredity (genetic dispositions) and environment (social and chemico-physical causes). In 1926 the distinguished biologist Julian Huxley wrote:

“Some genes control colour, others height or weight, others fertility or length of life, others vigour and the reverse, others shape or proportions. Possibly all, certainly the vast majority, of hereditary characteristics are gene-controlled[?]. For mental characters, especially the more complex and subtle ones, the proof is more difficult, but there is every evidence that they are inheritable, and no evidence that their inheritance is due to a different mechanism from that for bodily characters. That which is inherited in our personality and bodily peculiarities depends somehow upon the interaction of this assorted battery of genes with which we are equipped at fertilization” (The Stream of Life).

What questions can science even tackle?
How or why we are thus equipped is not discussed, as science has little to say beyond simple empiricism. To say that it is mere “chance” is the same as saying that there is no reason for it at all.

One may be read to admit that the phenomena revealed by science are partly instrumental as mechanisms more than actual "causes." Could mechanisms be solely responsible for the subtle distinctions that exist among individuals? Why should identical twins physically alike by virtue of inherited genes -- enjoying the same privileges and disadvantages of upbringing -- be temperamentally, morally, and intellectually different?

Heredity alone cannot account for the vast differences we observe. Strictly speaking, it would account more plausibly for a few of the similarities than for most of the differences.

The minute chemico-physical germ (fertilized ovum) inherited from parents, thought to be about 30 millionth of an inch across, explains only a portion of a person, that is, the physical foundation.  With regard to the more complex aspects, one can search and search the environment and still not find a satisfactory explanation. Karma -- when understood correctly rather than assumed to mean immediate mechanical cause-and-effect as postulated by Newtonian physicists -- provides just such a satisfactory, and at least personally verifiable, explanation.

Just sitting when I should be doing?

Wisdom Quarterly (EDITORIAL)
Budai the Happy Bodhisattva sits joyfully (Muffett68 flickr.com)
  
"Don't just do something; sit there!" it is said.

How could sitting -- intentional action that's mental -- trump physical and verbal action?

I want to protest, I want to cry out, I want change the world!

Budai (Shutterhound Photography/flickr)
Can I  even change that world? That remains to be seen. We keep trying. But while we fret and fuss, the one sure person we could be changing goes unchanged.

Who can save another? Help another, yes, of course. But who can save, who can do it for another -- "it" being cultivate absorption as the basis of successfully liberating-insight (i.e., walk the Path of Purification)?

No one saves us but ourselves.
No one can and no one may.
We ourselves must walk the Path;
Buddhas only point the Way.

Why are we searching when the Path is known? What are we waiting for? Step 1, Step 1, what is Step 1?

Giant Buddha, Leshan (tenlivingcities.org)
One way to understand the very packed (densely encoded) message of the Noble Eightfold Path is to follow it as a threefold teaching: 1) right view (wisdom), 2) virtue, and 3) meditation (concentration, that is, the effortless composure of mind, which like the hang gliding after all the effort of launching).

This is not a step-by-step path: Its factors or folds are cultivated simultaneously. So as we increase in virtue, our ease, joy, and concentration improves. This gives rise to wisdom as the mind/heart settles and we are able to see things more clearly just as they are.

The Truth is just as it is. We need not contort ourselves to "believe" it. We need only watch and withhold biases (distortions), evaluations (views), and opinions. The Truth sets one free. We need do nothing more than find that truth by rectifying ourselves rather than the world. "Don't just do something; sit there."

Science Studies Daydreaming Brain



"Surprise! Daydreaming Really Works the Brain"

Got a tough problem to solve? Try daydreaming.

Contrary to the notion that daydreaming is a sign of laziness, letting the mind wander can actually let the parts of the brain associated with problem-solving become active, a new study finds.

Kalina Christoff of the University of British Columbia in Canada and her colleagues placed study participants inside an fMRI scanner, where they performed the simple routine task of pushing a button when numbers appear on a screen. The researchers tracked subjects' attentiveness moment-to-moment through brain scans, subjective reports from subjects, and by tracking their performance on the task.

Until now, scientists had thought that the brain's "default network," which is linked to easy, routine mental activity, was the only part of the brain that remains active when the mind wanders. But in the study subjects, the brain's "executive network" — associated with high-level, complex problem-solving — also lit up. More>>
