not that which is breathed into being.
I often think about this as a way to conceive of meditation in the mystical sense.
The breath is the thing — the prime mover. The meat that forms around it and generates the electrical impulses that form sensation, thoughts, and the construct of self, are mere by-products of the breath, which is a function of a kind of will exterior to consciousness.
I have found that this thought experiment (or is it, perhaps, a fundamental truth of existence?) helps facilitate achievement of the meditative state.
