Robert Monroe was a very interesting person. He was a business and media technology man in a sense who accidentally stumbled into something extremely metaphysical and controversial, out-of-body experiences.
Monroe's statements are a great listen for anyone interested in the subject.

The Monroe Institute link was founded by Monroe and carries on today with a mission of education, global awakening, and expanded consciousness.
