I am not writing an anatomy book, nor a dissection manual, though I do use anatomical terms when they’re clearer than everyday language. This isn’t a book about scientific knowledge. If you’re looking for detailed anatomical information, there are plenty of great books to choose from. This is simply the story of my personal experience in dissection lab, facing cadaver, and how that experience has shaped my perception of who I am and how I relate to everything—especially my body, in this lifetime.

I once read about a meditation technique where you lie on your back and imagine your body gradually decomposing until it becomes a skeleton. I also learned that in Buddhism there is a practice called  Charnel Ground meditation, where you observes your body from the inside and outside while watching a real corpse decay. I found it intriguing, interpreting it as training to recognize that all material existence—including our own bodies—is just a mere fleeting phenomenon—no different from a decaying corpse. 

In Japan, we have kusozu, a traditional set of painting depicting nine stages of a body’s decomposition. It’s our version of memento mori. The paintings show the slow decay of a beautiful woman’s body, eaten by animals, reclaimed by nature, until it’s reduced to dry, white bones scattered on the ground. It’s a reminder that my body, too, is impermanent and transient.

When we experience unbearable trauma, our consciousness may dissociate from our body to protect us. The body becomes an object that performs a specific function, separated from the ”I” consciousness.  When I had sessions with a Zen psychology therapist, he often asked, “What do you feel in your body?”  Each time, I would look up at the ceiling, glance around the room, and search for the answer outside of myself. “Can you feel your feet on the floor?” he asked. While I could physically sense my feet touching the ground, that sensation felt completely disconnected from what I was feeling mentally.

I had little understanding of my own body. Even when I meditated on a corpse, I struggled to visualize it clearly.  With no conscious connection to my body, the corpse quickly became a mere abstraction of bones. I couldn’t grasp how complex and delicate the human body was, nor how it was related to my very existence.

Through gross anatomy training, I gradually restored the connection between myself and my body. Each time I stood at the dissection table, it felt as though I was slowly reclaiming my humanity. It has been more than ten years since I was initiated into human dissection, and I’ve spent over 1,500 hours in dissection labs. Now attending an annual dissection workshop feels like a Zen practitioner returning to the temple—a form of spiritual practice. It prepares me for the reality of death and dying, and reminds me of the importance of living fully in the present moment. 

In yoga, Savasana is the pose where you lie on your back, imitating a corpse. When we approach a dissection table in the lab, we face a donated body quietly resting in Savasana pose—the final posture we will all eventually take.
