" All that I know is that I am.

I can know that the self is not me, because I can inquire into it, deconstruct it until it seems to dissolve, or just leave it alone, and yet I still exist. The body is not me, because it appears, changes, and eventually ceases to exist. Consciousness, too, is heir to movement and impermanence, and I am not solely that either. What remains when all else is removed is the silence that is a still, infinite, boundless, permanent, un-cancellable nothingness from which all springs.
And this Absoluteness never changes. 

I can only say that I am this. "
