Gray Matters

'''Hjortsberg, William. Gray Matters'''. New York: Simon, 1971.

In WH's future world, humankind have given up their bodies to live as brains in a huge hivelike complex. Here they go through a process of emotional purgation and perfection intended to prepare them for "Nirvana," when they will be granted use of perfect bodies grown to receive their perfected brains. See J. T. Sladek, The Müller-Folker Effect and the works crosslisted there.
