Restricted Environmental Stimulation

John C. Lilly

“Lilly's isolation tank — the method behind every float session in File 004.”

Esalen-era REST put a body in saturated Epsom salt and turned sensory reduction into a timed protocol. Commercial tanks followed; the session is still Lilly's.

Opened flotation as a named method, not a novelty bath.
