There is nothing at all that can be talked about adequately, and the whole art of poetry is to say what can't be said.
Alan WattsTry to imagine what it will be like to go to sleep and never wake up... now try to imagine what it was like to wake up having never gone to sleep.
Alan WattsBut nirvana is a radical transformation of how it feels to be alive: it feels as if everything were myself, or as if everything---including "my" thoughts and actions---were happening of itself. There are still efforts, choices, and decisions, but not the sense that "I make them"; they arise of themselves in relation to circumstances. This is therefore to feel life, not as an encounter between subject and object, but as a polarized field where the contest of opposites has become the play of opposites.
Alan Watts
