Yoga

Indian yoga, with its emphasis on the transmutation of energy to higher consciousness, was the chief contributor to the cultivation of kundalini and the preservation of its knowledge prior to present times. Kundalini was a rarity in the West before the 1970s until more attention became centered upon the consciousness. In 1932, for example, psychiatrist Carl G. Jung and others observed that the kundalini experience was seldom seen in the West.

However, an examination of mystical literature and traditions showed that kundalini, called by various names, seems to have been a universal phenomenon in esoteric teachings for perhaps three thousand years. Kundalini-type descriptions or experiences are found in esoteric teachings of the Egyptians, Tibetans, Chinese, some Native Americans, and the !Kung bushmen of Africa. Kundalini has been interpreted from the Bible as "the solar principle in man," and is referenced in the Koran, the works of Plato and other Greek philosophers, alchemical tracts (the philosopher's stone), and in Hermetic, Kabbalistic, Rosicrucian, and Masonic writings.
