Consciousness, shamanism, mind-body medicine, mental imagery, altered states of consciousness, anomalous cognition, parapsychology, Jeanne Achterberg, Ruth-Inge Heinze, Stanley Krippner


Following the previous homage to Charles T. Tart and considering that Stan Krippner has celebrated more than 90 birthdays, this issue commemorates Stan along with two consciousness trailblazers who collaborated with him while they were alive: Jeanne Achterberg and Ruth-Inge Heinze. Jeanne was a very influential pioneer in mind/body medicine, particularly imagery in healing. Ruth-Inge Heinze had a deep commitment to the study of shamanism and promoted its interdisciplinary study in many ways. Finally, Stan Krippner is the quintessential liminal figure with made major contributions to the study of dreams, anomalous cognition, personal mythology, and other consciousness areas.
