Karma

Karma, Anyone? In Fact: Everyone!

The Buddha knew nothing about evolution, but karma is “right on”
I’ve been writing about karma, not as traditionally perceived by originalist Buddhism, but as something that coheres with modern biology—specifically, the idea that just as Buddhists see karma as being inherent in the nature of the universe, evolutionary biologists perceive evolutionary connectedness as fundamental to all life. Moreover, and at least as significant, just as Buddhists see living beings as created by and therefore a consequence of their karma, evolutionary biologists know that living things have been created by and are therefore a consequence of the selective pressures that have operated on the genetic streams that have preceded the current instantiation of all life forms as they currently exist. In this crucial sense, for Buddhists and biologists alike, we are precisely the consequence of our karma.
We can of course go further, as both biology and Buddhism do, and base a science as well as a world-view on the fact of genetic connectedness—not only among members of the same species, but also among all living things: Genes for most fundamental biological processes are very widely shared, and thanks to evolutionary continuity combined with natural selection’s favoring of some genes over others, the more fundamental the impact of particular genes, the greater the sharing. All vertebrates, for example, are more than 95% karma-connected when it comes to genes that underwrite cellular metabolism, for example. Moreover, the mechanisms whereby genes are integrated into organisms are themselves widely shared, which is why it is possible for biologists to introduce, say, genes for cold-resistance found in deep sea fish into tomatoes. Our evolutionary bequeathal is, in an almost literal sense, our karma. Since we are mammals, we have a different karma than if we were haplodiploid insects such as bees or ants.
The pattern is well known to anyone with a smidgeon of biological sophistication: Homo sapiens (to take just one species, admittedly not at random) share nearly all their genes with other primates, although more with the other apes than with baboons or macaques. And we share more genes with other mammals than with birds, reptiles or fish. And more with other vertebrates than with, say, dragonflies or dung beetles. And so on: A pattern of variation in genetic identity, decreasing in intensity as the focus expands, but nonetheless with no qualitative discontinuities. This is karmic continuity indeed, as each widening circle, incorporating individuals who are progressively more distantly related, represents a diminishing probability of genetic identity and accordingly, less evolutionary self-interest.
When it comes to the moral implications of karma, the matter is somewhat more complicated, and if anything, more interesting. On the one hand, there is much to be said for debunking the oversimplified (and widespread) idea that karma is something that gets attached to our “selves,” a notion that is unreliable on several levels. Thus, it presupposes the existence of a separate and independent self. And it raises, moreover, the problem of how, exactly, does any kind of karma—good or bad—get itself attached to something as slippery as the ostensible human soul. Cosmic glue? Magical vibrating tendrils of invisible, sub-organismic connectivity? Of course, a similar problem inheres with the Christian and Islamic sense of sin, generally conceived as some sort of semi-indelible stain, somehow imprinted upon the soul.
There is also the problem that karma can have a downright ugly side, justifying bad events. Why are some people terribly poor, sick, the victim of accident, crime or abuse? Well, they must have had terrible karma; in other words, they deserve it because of transgressions in a prior life! Not surprisingly, in some Asian societies, karma has a history comparable to the West’s use of Social Darwinism to “explain” (and in the process, justify) the perpetuation of monarchies as well as trodding upon the already down-trodden.
In a world of profound inequity, unfairness and undeserved suffering, I at least categorically refuse to accept that personal or social justice is somehow woven into the fabric of the world, whereby accumulated “bad karma” reveals itself in the suffering of those who seem innocent but who actually misbehaved in a prior incarnation and are therefore getting their just desserts at present. And vice versa, of course, to those born into hereditary wealth and position.
I am thinking of a haunting poem by Thich Nhat Hanh—titled “Please Call Me By My True Names”—that included, as perhaps its most noteworthy image, a young Vietnamese girl who had been raped by a sea pirate and who suicides as a result. Most startling is how Hanh puts the “blame” not only on the rapist pirate but also, notably, on the poet himself and by extension, all of us. By contrast, traditional Buddhist (and Hindu) teaching about karma would place a large share of the responsibility on the young and—by any reasonable standard—innocent victim. I trust that most readers of this blog, and of my recent book, “Buddhist Biology,” would agree that such a perspective is abhorrent.
But this doesn’t mean that Buddhist karma is wholly to be discounted. In fact, I hope to convince you that the exact opposite is true: Karma is real, not as a mystical guiding principle for the reincarnation of souls, or some such poppycock, but as something scientifically valid, closer to the Dalai Lama’s invocation of the law of cause and effect, and to Thich Nhat Hanh’s emphasis on the extent to which our interconnectedness combined with the relevance of action demands that we accept responsibility rather than blame the victim. In fact, I believe a strong case can be made that once we step away from its superstitious dimensions, there is no such thing as a karma-free zone, and that in the realm of karma—as with the other foundational Buddhist concepts we have investigated—there is deep convergence between Buddhism and biology, and that in turn, this has profound moral consequences, notably when it comes to responsibility for our own actions. This is especially true insofar as our karma is something that we create, by virtue of how we choose to live.
And this, in turn, opens the door to an another unexpected convergence: not only between Buddhism and biology, but between “Buddhist biology” and existentialism. More to come.

Meditation as Medicine

Meditation as Medicine for Loneliness

A recent study finds that meditation can be neuro-therapeutic
A recent scientific report suggests that Buddhist-style meditation has a discernible (and beneficial) effect on brain function, especially among elderly people suffering from various consequences ofloneliness and depression. Before describing and commenting on this finding, I would like to note that one of the most appealing aspects of Buddhism (at least for me) is its compatibility with science. According to the Dalai Lama,
“Suppose that something is definitely proven through scientific investigation, that a certain hypothesis is verified or a certain fact emerges as a result of scientific investigation. And suppose, furthermore, that this fact is incompatible with Buddhist theory. There is no doubt that we must then accept the result of the scientific research.”
The comfortable fit between Buddhism and empirical science has been facilitated by several teachings, of which perhaps the most important is the “Kalama Sutra.” In it, the Buddha advises his audience (people known as the Kalamas) how to deal with the bewildering diversity of conflicting claims on the part of various Brahmins and itinerant monks:
“Do not go upon what has been acquired by repeated hearing; nor upon tradition; nor upon rumor; nor upon what is in a scripture; nor upon surmise; nor upon an axiom; nor upon specious reasoning; nor upon abias towards a notion that has been pondered over; nor upon another's seeming ability; nor upon the consideration, 'The monk is our teacher.' Kalamas, when you yourselves know: 'These things are good; these things are not blamable; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness,' enter on and abide in them.”
These words of the Kalama Sutra are not only quite straight-forward, they also fit nicely into the Western scientific tradition: The Royal Society of London, whose full name was the Royal Society of London for the Improvement of Natural Knowledge, and which was the world’s first – and for a long time, the foremost – scientific society, has as its credo, Nullius in verba – “On the words of no one.”
My own interest in the science-Buddhism interface has focused not on the already well-traveled (and, I fear somewhat fanciful) avenues that purportedly link Buddhism to quantum physics, or even on currently popular elaborations of how meditation impacts the human brain, but rather, what I see as something deeper and more ultimately consequential, namely the notable convergences between Buddhism and biology more generally, especially in the realms of ecology, evolution,genetics, and development.
For his part, the Dalai Lama has long had a genuine scientific interest in mind-brain correlations, such that he was the invited plenary speaker at the huge Society for Neuroscience annual meeting in November, 2005. He eventually spoke on “The Neuroscience of Meditation,” but before doing so, his very invitation caused an uproar. There was a protest petition, which garnered about 1,000 signatures, mostly from scientists worried about religion invading science, and thereby degrading it. In any event, his lecture touched on something that has also received a great deal of attention, probably much more than it deserves: namely, the question of whether meditation actually causes bona fide changes in brain function among those who engage in it. Evidently, it does.
The recent study that generated the piece you are now reading thus fits into a rapidly developing tradition linking neurobiology and meditation. Indeed, the scientific world – and not just that of lay-persons – was abuzz some time ago when a group at the Waisman Laboratory for Brain Imaging and Behavior at the University of Wisconsin in Madison, led by professor of psychology Richard J. Davidson, reported in the Proceedings of the National Academy of Sciences (probably the most prestigious scientific publication in the US), that Tibetan Buddhists who had practiced serious meditation for many years had brain-wave patterns that differed consistently from those of a non-meditating control group.
But why should anyone have been surprised? The meditators had engaged in years of prolonged and, indeed, arduous mental training, which involved from 10,000 to 50,000 hours of serious meditation. Compared to “healthy student volunteers,” they exhibited “high-amplitude gamma synchrony.” Wouldn’t it be even more surprising if such experiences didn’t generate some sort of discernible effect in their brains?
If you examine the brain functioning of people who have been watching seven hours of television per day, I daresay you would find changes in their cerebral functioning, too. Ditto for anyone reading this post, or yearning to scratch an itch. The point is not to “disrespect” any of the growing pile meditation-neurobiology research results, but to note the degree to which even educated, scientifically sophisticated individuals remain incredulous at the revelation that mind and brain are connected. Somehow, the very fact that meditation generates reportable brain changes continues to be widely seen as making this ancient Buddhist practice more legitimate. In my simple and not-so-humble opinion, such legitimation is simply not needed.
Although it is interesting.
Most intriguing, in the case of the research that prompted the written meditation you are now reading – and which was titled “Mindfulness-Based Stress Reduction Training Reduces Loneliness and Pro-inflammatory Gene Expression in Older Adults: A small randomized controlled trial” – is the fact that meditation appears not only to exert an effect on the brains of meditators (as already noted, no surprise there!), but that the impact seems to be medically beneficial (once again, no surprise here, either, at least for those of us who already know, via our own subjective experience, that meditation feels good). It is certainly notable, however, that meditation is actually therapeutic in these cases, if only because such practise – even when conducted in the presence of others – is necessarily solitary, or at least, inward-looking. Hence, it would not have been surprising if meditation, at least when conducted by individuals who had lacked prior experience in the practise, had actually experienced a short-term increase in dukkha.
Evidently, part of this beneficent impact occurs via the impact of meditation on “gene expression,” which simply means that the particular experience of meditating impacts whether certain genes become activated, and/or to what extent. This, too, is to be expected, since the current state of biological knowledge suggests that gene activation is one of the most common mechanisms whereby experiences induce biochemical consequences.
I don’t mean to minimize or in any way demean this finding in question, and certainly not the value of meditating! Although I am not a neurobiologist, my reading of the research findings strongly suggests that the results are genuine: the experimental design was apropriate, as were the statistics employed, although a larger sample size will be needed to confirm that they are “robust,” before concluding that meditation should be added to the medical armamentarium of those seeking to ameliorate some of the more painful effects of aging and loneliness. Without going into the biochemical details, it seems that meditation inhibits the release of “pro-inflammatory” molecules, and that such inhibition increases the subjective well-being of sufferers. To quote the study’s authors, “This work provides an initial indication that [Mindfulness-Based Stress Reduction] may be a novel treatment approach for reducing loneliness and related pro-inflammatory gene expression in older adults.”
In her essay, “Six kinds of loneliness,” Pema Chodron wrote that
“we regard loneliness as an enemy. Heartache is not something we choose to invite in. It’s restless and pregnant and hot with the desire to escape and find something or some-one to keep us company. When we can rest in the middle [of meditation], we begin to have a nonthreatening relationship with loneliness, a relaxing and cooling loneliness that completely turns our usual fearful patterns upside down.”
If the research finding herein discussed holds up, care-givers will have gained an additional technique – inexpensive, non-threatening, lacking in negative side-effects – to help restrain those “fearful patterns” of heartache, thereby reducing the world’s pain and suffering (dukkha, in Buddhist-speak) in a meaningful and skillful manner.
