Zazen is non-doing, and this non-doing, say the Zen Masters (Dogen among them) frees us.
Is it, then, doing that ensnares us?
Is it non-doing that loosens all bonds?
Is it non-doing that opens all gates?
Is it non-doing that lets in the light?
Is it non-doing that gravitates toward the original face, before the doing?
I have asked myself this question many times: how deep does our doing run? Does a constant, subliminal doing keep memory—with all its images of sights, sounds, smells, tastes, touches and mind experiences—alive and in place, ready for harvesting at any given moment.
Does a constant, subliminal doing keep us glued to the body (apparently inside the three pounds of living flesh we call the brain)? Are we, in fact, holding on to the brain and body much like the desperate, shipwrecked sailor clinging to flotsam to stay alive? Are we constantly creating and keeping in place the very bars that comprise our cage?
If this were so, and we knew it were so, we could cease, let go. But how can you cease, how can you let go of something that you are not aware of creating or clinging to? That is the pivotal question.
Meditation, I believe, lets you in on the secret, makes you aware: you are holding on, you are creating those mental bars and form your cage. And now aware, you can let go.
This letting go lets in the light.
