Kundalini yoga is an Indian discipline designed to awaken the body's energies and promote enlightenment. Tantric sex also makes use of Kundalini energy to achieve unity between the practitioners and the Hindu goddess of feminine power. Astral travel describes any activity during which the soul or life force travels outside of the body. The hippie culture of the '60s, embracing diversity, Eastern religions and the sexual revolution, would be eager to learn these practices.
