arises. This has a beneficial effect on the health of the physical body. The fifth circuit is consciousness of the body. There is a marked shift from linear visual space to an all-encompassing aesthetic sensory space. Perceptions are judged not so much for their meaning and utility, but for their aesthetic qualities. Experience of this circuit often accompanies an hedonistic turn-on, a rapturous amusement, a detachment from the previously compulsive mechanism of the first four circuits. This circuit is activated by ecstatic experiences via physiological effects of cannabis, Hatha Yoga, tantra and Zen meditation. Robert Anton Wilson writes, "Tantra yoga is concerned with shifting consciousness entirely into this circuit" and that "Prolonged sexual play without orgasm always triggers some Circuit V consciousness". Leary describes that this circuit first appeared in the upper classes, with the development of leisure-class civilizations around 2000 BC. Sixth Circuit Leary labelled this the Neuro-Electric Circuit and Wilson called this the Metaprogramming Circuit. Timothy Leary listed this circuit as the sixth, and the neurogenetic circuit as the seventh. In his Prometheus Rising, Wilson reversed the order of these two circuits, and described neurogenetic circuit as the sixth circuit, and the metaprogramming circuit as the seventh. In Quantum Psychology, published later, Wilson reverted the order back to Leary's original schema. This circuit is concerned with reimprinting and reprogramming the earlier circuits and of perceiving the relative (versus absolute) nature of the "realities" perceived by them: the sixth circuit becomes aware of itself. Leary thought that this circuit enables telepathic communication. He believed that the circuit was activated by 50-150 μg LSD, moderate doses of peyote, psilocybin mushrooms and meditation/chanting especially when used within in a group or ritual setting. Leary estimated that this circuit came "online" in 500 BC. Seventh Circuit Leary referred to this as the Neurogenetic Circuit. Wilson called this the Morphogenetic Circuit. (Wilson here made reference to Rupert Sheldrake's morphogenesis theory.) This circuit is the connection of the individual's mind to the whole sweep of evolution and life as a whole. It is the part of consciousness that echoes the experiences of the previous generations that have brought the individual's brain-mind to its present level. It deals with ancestral, societal and scientific DNA-RNA-brain feedbacks. Those who achieve this mutation may speak of past lives, reincarnation, immortality etc. It corresponds to the collective unconscious in the models of Carl Jung where archetypes reside. Activation of
