Consciousness fertilised by particularity gives birth to experience. Experience belongs to a self and is directed towards a not-self, in doing so it gives rise to feeling, perceiving, thinking, knowing etc. all of which are directed towards the enigma of the not-self. The not-self is revealed to be the other-self, or simply the other, which in the midst of irreversible complexification of experience, the universal expansion, first opens the possibility of a return to the source, of a possibility hidden within particularity. You might wonder whether experience is merely one contingent possibility of consciousness? But, no, it is latent in the undifferentiated plenum of original consciousness in a special way.
