"It may perhaps help us to realize the human side of our Masters if we remember that many of Them in comparatively recent times have been known as historical characters. The Master K. H., for example, appeared in Europe as the philosopher Pythagoras. Before that He was the Egyptian priest Sarthon, and on yet another occasion chief-priest of a temple at Agade, in Asia Minor, where He was killed in a general massacre of the inhabitants by a host of invading barbarians who swooped down upon them from the hills... Again, in these researches into the remote past we have frequently found the disciple Jesus, who in Palestine had the privilege of yielding up His body to the Christ. As a result of that act He received the incarnation of Apollonius of Tyana, and in the eleventh century He appeared in India as the teacher Ramanuja, who revived the devotional element in Hinduism, and raised it to so high a level."
