Kundalini is a Sanskrit word that has become familiar in the western world now and is associated with various types of meditation practice. H.P. Blavatsky described Kundalini as "The power of life; one of the Forces of Nature; that power that generates a certain light in those who sit for spiritual and clairvoyant development. It is the power known only to those who practise concentration and Yoga." This PowerPoint presentation will look at what theosophical writers have to say on this subject and examine the role Kundalini plays in the Cosmos and in ourselves.
