Serapis Bey is one of the 'Great Masters' of the New Age Movement. Known as the great disciplinarian, he reviews and trains candidates for the ascension. It is also thought that Serapis Bey worked closely with the other Great Masters such as Morya, Kuthumi and Djwal Kul to help found the Theosophical Society.
The Egyptian pharaoh Amenhotep III, c. 1417-1379 b.c., called "the Magnificent," was believed to have been "embodied" by Serapis. He brought Egypt to its height of prosperity. His extensive building of monuments, palaces and temples included construction of the temple of Luxor, which was thought to have been built to correspond to the outline of the human skeletal framework. Study of its architecture have been said to have revealed that the entire temple explains many secret functions of the organs and nerve centers.
Serapis Bey supposedly "ascended" in about 400 b.c. Then New Age Believers say that in 1967, the Ascended Master Serapis Bey dictated the book Dossier on the Ascension: The Story of the Soul's Acceleration into Higher Consciousness on the Path of Initiation, which was recorded by the Messenger Mark L. Prophet. In this book, Serapis offers profound answers to the questions of life after death. He outlines step by step how to follow the adepts of East and West, including Jesus Christ, "who have been candidates at the mystery school of Luxor, Egypt, submitting to the initiations of the Sphinx and the Great Pyramid". Serapis teaches how to consciously ascend (accelerate) into that 'higher reality', quickening the evolution process of becoming a Great Master.
