In 1955, he met the famous Brazilian medium Chico Xavier and the two co-authored several books on Spiritism, founded their Spiritist centre, practiced philanthropy and did voluntary medium work, including psychographies. Around 1966, he became a dissident Spiritist, developing his own views on the subject and stopping to work with Xavier. He then began studying themes related to parapsychology, like astral projections and altered states of consciousness. He became a member of the American Society for Psychical Research and the Society for Psychical Research, founding two fields of study he termed Conscienciologia ("Conscientiology") and Projeciologia ("Projectiology").
