Elizabeth Lesser, co-founder of the Omega Institute calls Dr. Charles T. Tart “one of the fathers of the New Age.”
I heard him speak to the Association for Spirituality and Psychotherapy a few years ago and was so taken with his knowledge of spiritual matters and his sweetness. A longtime meditator who puzzles out his own conscious states, Tart has involved himself with the research and theory of hypnosis, psychology, transpersonal psychology, parapsychology, consciousness, and mindfulness since 1963. He has written more than a dozen books and 250 articles, including lead pieces in the periodicals “Science” and “Nature.”

Tart currently collects and posts online narratives of the spiritual experiences of scientists and those predisposed to be tangible-evidence-seeking skeptics, people not inclined to believe in the divine. You’ll find Tart’s most recent menu of spiritual samplings here.
Here’s a link to a recent post on fire-walking that includes Tart’s own story of his experience with it. Fact: The coals CAN burn you if your head isn’t on straight.
Many more spiritual narratives are archived here. Each one is its own CM blog item, with its own point to ponder, but I’ll let you poke around and enjoy the write-ups as you find the time. Enjoy!
