Eternea - The center for research and education concerning Spiritually Transformative Experiences (STEs) -- an organization I co-founded with John Audette (with great assistance from Raymond Moody, Edgar Mitchell, Bill Guggenheim, Bob Staretz, Ken Ring, Elizabeth Hare, and others) to convert the enthusiasm and passion generated by my book and presentations into a much better world through research, education and enlightenment - all towards the synthesis of science and spirituality for the benefit of all mankind.
Sacred Acoustics - Advanced auditory enhancement of deep meditation, exploration of transcendental conscious states
