'Kundalini' is the Indian word for a spiritual energy known by a variety of titles to many cultures - 'Shekinah' in mystical Judaism, 'Sekhem' in Egypt, 'Da Kan Li' in Daoism. Present throughout the universe, Kundalini is thought to lie quiescent in most humans at the base of the spine. In this book, Dr. Arundale gives a clear, concise and very personal account of this powerful force which, when aroused, migrates up the spine, vivifying successive chakra until reaching the crown - when it bestows 'enlightenment' of long or short duration. Dr George S Arundale spent many years in India studying its spiritual traditions, and working alongside such luminaries as Annie Besant. He was principal of the Central Hindu College in Varanasi, and in 1934 was elected as president of the Theosophical Society, a post he held until his death in 1945.
