This book tells the inside story of Learys early LSD research at Harvard. Known throughout the world as the guru who encouraged an entire generation to turn on, tune in, and drop out, he draws on wit, humor, and skepticism to debunk the power of psychotherapy and to advocate reprogramming the brain with psychedelics. Discussing how various drugs affect the brain, how to change behavior, and how to develop creativity, he also delves into psychopharmacological catalyzing, fear of potential, symbol and language imprinting, and brain reimprinting with Hinduism, Buddhism, and LSD.
