"They became futile in their reasoning."
The realization,"I am formless consciousness" is simply the opposite of "I am an individual somebody." Even with that realization, there is still going to remain the appearance of somebody. So embodiment is simply a reflection of the realization that every manifest thing that exists is the one body of the one consciousness. This is a return to wholeness, to a completeness that includes the unmanifest and the manifest alike. It is perceiving that both formless consciousness and the world of form are simply two aspects of an unnameable mysterious whole.
