Ascended masters in the Ascended Master Teachings of a number of movements in the theosophical tradition are held to be spiritually enlightened beings who in past incarnations were ordinary humans, but who have undergone a series of spiritual transformations originally called initiations. Both "mahatma" and "ascended master" are terms used in the Ascended Master Teachings. Ascended Master is based on the theosophical concept of the Mahatma or Masters of the Ancient Wisdom. However, Mahatmas and Ascended Masters are believed by some to differ in certain respects. According to the Ascended Master Teachings a "Master of Light", "Healer" or "Spiritual Master" is a Divine Human Being who has taken the Fifth Initiation and is thereby capable of dwelling in a 5th dimension. The teachings hold that an "ascended master" is a human being who has taken the Sixth Initiation, also referred to as Ascension, and is thereby believed to be capable of dwelling in a 6th dimension. The term "ascended master" was first used by Baird T. Spalding in 1924 in his series of books, Life and Teachings of the Masters of the Far East (DeVorss and Co.). Godfre Ray King (Guy Ballard) further popularized this concept of spiritual masters who had once lived on the earth in his book Unveiled Mysteries. Definition Adherents of the Ascended Master Teachings hold that this belief was partially released by the Theosophical Society beginning in 1875, by C.W. Leadbeater and Alice A. Bailey, and began to have more detailed public release in the 1930s by the ascended masters through Guy Ballard in the I AM Activity. However, theosophists maintain that the concept of ascended master is an exaggeration and corruption of the more modest theosophical concept of "Master of the Ancient Wisdom". Guy Ballard said his work Unveiled Mysteries was dictated to him by the ascended master St. Germain. Other Ascended Master Teachings are contained in The Bridge to Freedom (1951), Mark Prophet and Elizabeth Clare Prophet's The Summit Lighthouse (1958) (reorganized as the Church Universal and Triumphant in 1975), The Temple of The Presence (1995), The Hearts Center (2005), the I AM University (2004), and various other organizations such as The White Eagle Lodge (1936) and the Aquarian Christine Church Universal (2006). Origins The founder of the Theosophical Society, Helena Blavatsky, in the late 19th century brought attention to the idea of secret initiatory knowledge, by claiming her ideas were based on traditions
