Psychiatrist Stanislav Grof developed the holotropic breathwork technique to simulate a psychedelic effect in the brain.
A wave of high-level peer reviewed clinical evidence now shows that psychedelics have far-reaching and profound application to a wide range of mental health disorders. Unfortunately, it will be many years before the FDA approves such drugs, not to mention the fact that they are illegal under the Controlled Substances Act. An alternative way to achieve a psychedelic state is rapid and deep breathing under the supervision of a trained expert. The mere change in oxygen levels in the brain for 60 minutes safely produces this effect with no drugs. Patients experiencing holotropic breathwork experience a sense of identity, called a transpersonal experience, where one feels a connection to the wider aspect of humanity, life and the cosmos. A flurry of new studies show how this state of consciousness, even for a short period, leaves lasting breakthroughs that would ordinarily take many years of talk-therapy to achieve.
“Materialistic scientists have not been able to produce any convincing evidence that consciousness is a product of the neurophysiological processes in the brain.”
