The rule of self-realization involves a progressive unfolding. The earlier, less self-aware levels of consciousness remain in place as a basis or foundation upon which to build, even when we overpass them with a new level of manifestation. The goal then becomes to transform that pre-existing basis of consciousness, rather than abandon it or deny its reality. This unifies the individual’s destiny with the general evolutionary impetus of consciousness in manifestation, aligning the individual with the Divine Purpose.
