This program was recorded during the late 1960s when the use of psychedelic drugs such as LSD and mescaline were becoming increasingly popular with the youth culture. Geoffrey Hodson talks about the altered states of consciousness associated with such drugs and compares them with the changes in consciousness brought about by a disciplined practice of Yoga. One difference is that expanded states of awareness brought about by drugs are temporary and often accompanied by great risk, whereas enhanced states of consciousness brought about by spiritual disciplines are retained by the practitioner. 1967. 33 minutes.
