Dr. Welton assigned me to the newest body, where dissection had just begun, and specifically to the left hand. He wanted tendons and ligaments exposed. Day after day, I took my tools and sat alone beside the table and carefully opened the hand, following diagrams in a thick book. I did a good job. I gradually came to understand that hand, and all hands, in a way that remains with me now. But I came to understand something else as well. One day, I had almost finished exposing the tendons. I found that by pulling on them gently, I could move the fingers one by one. I had never been uneasy in that room, but that day I looked up the length of the body, naked except for the covered face, and all at once I was covered in goose bumps.

Dissection is more a psychological experience than an intellectual one for many people. I found it to be both. I remember more about how it felt to be with the dead, to touch and open a body, to see what happens to bodies, than any details about the insertion of the latissimus dorsi muscle. (I learned that, too, in a way I could never have learned from books.) Working with cadavers makes it clear what death is. A subject becomes an object. A person becomes a body. And, miraculously, turns back: this body, this firm, immobile object, is, was, a person, a warm, breathing person. A body is not an ordinary object—can never be an ordinary object. This particular object had once been awake.

With a jolt, I realized that what I was cutting apart had been a living hand, just like mine; that it had been pliant and animated. It had held a pen, shoveled dirt, bathed a child, stroked someone’s hair. That it was like my precious hands, which until that moment had simply been part of me. Alive. I realized, This man is like me. I already knew that this body was like my body; I could label its parts. But suddenly I knew that this man was like me. And that I would be like this man.

Sallie Tisdale, Advice for the Dying (and Those Who Love Them): A Practical Perspective on Death

Sallie Tisdale’s recollection of her Anatomy and Physiology course is one of those passages that is especially precious to me. I cannot quite remember – it was long before my formal split from Christian faith and practice – precisely when it was I realised for myself, with perfect immediacy, that I was my body; my body was me, and one would not survive the other. It was sometime during the period when I was very ill with coronary heart disease, certainly, and, with the utter sense of reality that seems to characterise such times, I saw that death was no more than a dissolution into light – the safest, most natural consummation imaginable. (This was no intellectual exercise, but a vivid, real experience more certain than life itself.)

Throughout Buddhist literature in particular there are many intimations of this “clear light”, most notably I think in Dzogchen, where it is an attribute of the Ground (gdod ma’i gzhi). (I have long felt that Tillich’s phrase “the ground of being” was perhaps closer to expressing the irreducible Istigkeit than anything else I’ve read.) The ground of being is there, and only there, when we come to an end of ourselves. It lies far beyond all we know as self, or other – though it can appear to us so utterly other that we are tempted to hide from it – and yet the way to it is inward, into the extreme depths of what we are.  The ground of being is no thing: it precedes thingness.

The ground is the end, that to which all things return. Kathleen Dowling Singh:

[Death] is the experience of ‘no exit,’ a recognition of the fact that the situation is inescapable, that one is utterly at the mercy of the power of the Ground of Being… Love is the natural condition of our being, revealed when all else is relinquished, when one has already moved into transpersonal levels of identification and awareness. Love is simply an open state with no boundaries and, as such, is a most inclusive level of consciousness. Love is a quality of the Ground of Being itself. In this regard and at this juncture in the dying process, love can be seen as the final element of life-in-form and the gateway to the formless.

Of course one cannot practice for death, at least not intentionally. But one can practice with death in mind. To sit in the bright stillness of shikantaza is no more than that.

That everything is included within your mind is the essence of mind… Even though waves arise, the essence of your mind is pure; it is just like clear water with a few waves. Actually water always has waves. Waves are the practice of the water. To speak of waves apart from water or water apart from waves is a delusion. Water and waves are one. Big mind and small mind are one. When you understand your mind in this way, you have some security in your feeling. As your mind does not expect anything from outside, it is always filled. A mind with waves in it is not a disturbed mind, but actually an amplified one. Whatever you experience is an expression of big mind…

Before we were born we had no feeling; we were one with the universe. This is called “mind-only,” or “essence of mind,” or “big mind.” After we are separated by birth from this oneness, as the water falling from the waterfall is separated by the wind and rocks, then we have feeling. You have difficulty because you have feeling. You attach to the feeling you have without knowing just how this kind of feeling is created. When you do not realize that you are one with the river, or one with the universe, you have fear. Whether it is separated into drops or not, water is water. Our life and death are the same thing. When we realize this fact we have no fear of death anymore, and we have no actual difficulty in our life.

When the water returns to its original oneness with the river, it no longer has any individual feeling to it; it resumes its own nature, and finds composure. How very glad the water must be to come back to the original river! If this is so, what feeling will we have when we die? I think we are like the water in the dipper.
