What is perceived as 'solid matter' during incarnate life is perceived during disincarnate life (and during direct contact with Metaphysical Objects) as 'dream-stuff.' Matter (including the body) is a set of 'cosmic dream-symbols' composed only of ENERGY behaving in fixed patterns, obeying the symbolic structure of the great Dream we are in.
A real grasp of material reality requires a knowledge of the SYMBOLIC 'MEANINGS' OF THINGS, and an accurate relating with them AS SYMBOLS rather than as 'blind, stupid matter.' Such intelligent relating with Material forces leads to accurate material results; health, wealth and peaceful integration into Nature.
