Students of Ascended Master Teachings organizations (also known as "Ascended Master Activities") believe that their doctrine has been given to humanity by the Ascended Masters, individuals believed to have lived in physical bodies, acquired the wisdom and mastery needed to become immortal and free of the cycles of "re-embodiment" and karma, and have attained their "ascension", a state of "one-ness" with God. This knowledge is believed to have previously been taught for millions of years only within "Ascended master retreats" and "Mystery schools".
It is believed by adherents of the Ascended Master Teachings that this wisdom 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 the concept of Ascended Masters are a corruption of the original Theosophical concept of the Masters of the Ancient Wisdom.
The term Ascended Master was first introduced in 1934 by Guy Ballard with the publication of Unveiled Mysteries, a book which he said 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, Inc. (2006).
