When the I dissolves, so does the body. All that remains is Awareness, without an I, without a body, without thought. This can be known, and seemingly ‘afterwards’, described as one would describe an ‘experience’ of oneness. But it isn’t an experience that the I has – the I ceases to exist. It ‘dies’ (never really did exist… ). That, and the body in which it ‘appears’ to reside, arise simultaneously in object consciousness (Awareness is ‘prior to’ object consciousness). Objects/object consciousness arise simultaneously (as ‘the ten thousand things’). They exist (it seems) ‘in’ Awareness. Awareness IS… independent of / prior to consciousness. But really there is no independent of nor prior to.
You may wonder how ‘I’ know this. I don’t, and therefore can’t tell you. Because there is no I. But it is known… here… and attempts like this, to describe it such that the thinking mind can understand (even the thinking mind that seems to be ‘here’), are futile.
So be it.
