Watched this today, thought it was worth sharing. I’ve been listening to and reading the work of Dr.Grof for several years now, and have always found him to be a very sincere, intelligent and credible researcher, author and advocate of what he calls “non-ordinary states of consciousness”. I’ll let what wikipedia said about him serve as introduction.
“Stanislav Grof (born July 1, 1931) is a psychiatrist, one of the founders of the field of transpersonal psychology and a pioneering researcher into the use of non-ordinary states of consciousness for purposes of exploring, healing, and obtaining growth and insights into the human psyche.”
Lots of other good vids on youtube if you’re interested in hearing more of his presentations and interviews.
