How the Insights of Neuroscience Can Aid Our Practice
By Paul Tingen
Until the 1980s, conventional wisdom in neuroscience held that the brain developed during childhood until it reached a fixed form that remained the same during adulthood. This belief in the brain’s static cellular circuitry gave rise to a very limited view of human consciousness, a “neurological nihilism,” in which consciousness was seen as no more than the byproduct of these fixed pathways. With the emergence of the computer, the analogy was made that the hardware of the brain determined and limited the software (our feelings and our thoughts).
However, due to pioneering research in the 1980s, most famously by Professor Michael Merzenich,2 this orthodoxy was turned on its head. Since then it has become widely accepted that the brain constantly rewires itself in response to changes in our feelings, thoughts, experiences, and the way we use our body. This phenomenon is referred to as the plasticity of the brain. In computer language, the software and the hardware inter-are: the software can shape the hardware, just as much as the other way around. Neuroscience today is governed by what is known as Hebb’s rule: “Cells that fire together wire together.” The brain gets less plastic as we grow older, but the capacity for rewiring remains.

Good morning, dear Sangha. Today is Tuesday, the nineteenth of June 2012, and we are in the Still Water Meditation Hall, Upper Hamlet. This is our nineteenth day of the twenty-one-day retreat.
Sitting here, I can hear the sound of the rain. I know that I’m with my Sangha, sitting together, enjoying this present moment. With mindfulness, this moment must be a happy moment.
The practice of non-thinking is the secret of success in meditation. When thinking settles in, you lose the first impres-sion of contact. You do not have much chance to be in the here and the now, and to be in touch with what is in your body and around you. Instead, just become aware of contact and feelings. In this way you can be in touch with the elements of nourishment and healing available in your body and in the environment, both physical and mental. Continue reading →
“Interbeing” is a new word invented by Thich Nhat Hanh (Thay), which he employs to explain the interconnectedness of all things in the universe. A sheet of paper, for example, is an interbeing as it is connected with a cloud through a chain of relationships. “Without a cloud, there will be no rain; without rain, the trees cannot grow; and without trees, we cannot make paper,” Thay writes in The Heart of Understanding: Commentaries on the Prajnaparamita Heart Sutra. Things that appear totally unconnected to most people—a sheet of paper and a cloud, in this example—become connected with each other in a relationship which Thay calls “inter-are.”
Technically speaking, interbeing can be regarded as what mathematicians call a “binary relation,” a relationship established on a set of elements by pair-wise comparison of them, defined in this case on the set of all things in the universe, including our consciousness. It is not difficult to see that the binary relation of interbeing satisfies the three laws of reflexivity, commutativity, and transitivity. First of all, it is obvious that anything inter-is with itself, albeit in a trivial sense of that word. Thus, the binary relation of interbeing satisfies the law of reflexivity, namely, xRx, where the symbol R designates the binary relation of interbeing. Continue reading →
