There is no “the one.” For there to be one, there must a something other.
There is no real separation. There is no real self. There is no real consciousness or awareness. Yes, wholeness can appear as an illusion of separation. That illusion appears as a self-referential confirmation that it is real and that it is a part of something that is equally real. That is why it is an illusion. Wholeness is neither real nor unreal. What seems to be happening is indivisible, non-located, incomprehensible, boundless, and contextless. The self is illusory because all of its claims are false. It’s not what it claims to be. It is the wholeness (as pointed to a couple of sentences back) appearing as an illusion of separation. That illusion is an obscuration of what is actually happening. The self is how no self seems to hide no self, for no reason. The revelation of wholeness or no self is the revelation of what self actually is. Before, self is everything. After, there never was a self, nor a before.
