He's well known for his long-distance ESP experiments - up to ten thousand miles - and for his research on the ESP channel - that is, an unknown energy which transmits ESP.

In the '70's, Osis conducted extensive laboratory experiments on out-of-body experiences. These involved perceptual, physiological (EEG), and physical measurements. Together with Dr. Erlendur Haraldsson, he conducted a large-scale survey of the experiences of dying patients in India, which provided data for cross-cultural comparison between India and the United States. They also studied psychic phenomena in selected Yogis, particularly Sri Sathya Sai Baba, in southern India.

Erlendur Haraldsson, Ph.D., was born in Reykjavik, Iceland, in 1931. After finishing his studies at the gymnasium (college), he worked for some years as a journalist and writer, traveling extensively in western Asis and India.

Having studied psychology at the German universities of Freiburg and Munich, Haraldsson received the diploma of psychology, a degree equivalent to the M.A. in America.

Haraldsson has conducted numerous research projects, has published widely in scholarly journals in America and Europe, and written four books. At the Hour of Death, which he wrote with Dr. Osis, has appeared in over twenty editions. Over a period of ten years he made several journeys to India to study the famous "man of miracles" Sathya Sai Baba. Haraldsson's thorough study of Sai Baba resulted in Modern Miracles (the English edition is titles Miracles Are My Visiting Cards) which has been highly acclaimed by critics and appeared in fourteen editions.
