The indelible reality at the level of soul is other minds, or rather other souls. The question here is not that of overcoming solipsism from the base of Cartesian self-certainty, but of gaining some kind of self-existence in a flux determined by forces and flows which originally collect around diverse centres not yet identified as alterity. This translated what is called psychological reality, and indeed it describes the world in which most of your time is spent, the habitation of forces and deliria of every kind. Self and other is not the primary opposition here, but is derived at one or two removes, while in experience selves and other selves are never separate but continually bleed into each other. That its metaphysics is the reverse of what is suggested by the physical world is one more of its veils and obfuscations. The doctrine of anatma or no-self is not about the abolition of the self-centre in this realm but the seeing through its mystifications in their entirety.
