"Much of what I have to say is already known, or if not known, easily available. Beginning in 1875, some of this information has already been published in books translated into many languages, and is available to anyone who takes the trouble to read them. ...Helena Petrovna Blavatsky, founder of the Theosophical Society, began the dissemination of this information...followed in 1924 by...Helena Roerich, through whom the Agni Yoga teachings were given to the world, and by...Alice A. Bailey, between 1919 and 1949. I have been able to bring these teachings up to date, to show what is actually happening in the process of the return of the Masters to the everyday world."
