All preceding Yogas, given from the highest Sources, took as their basis a particular aspect of life. Now, at the dawn of the age of Maitreya, there is needed a Yoga comprising the essence of the whole of life, all-embracing, evading nought. One remembers the example of those unignitible youths in the biblical legend who valiantly sacrificed themselves to the fiery furnace and thereby acquired power.
You may call this the Yoga of Life. But the most precise name will be Agni Yoga. It is precisely the element of fire that gives its name to this Yoga of self-sacrifice. While in other Yogas the dangers are diminished through practices, in the Yoga of Fire the perils are increased, because fire, as an all-binding element, manifests itself everywhere. But it also permits mastery of the subtlest energies. Fire will not lead away from life; it will act as a trustworthy guide to the far-off worlds. For what but fire saturates immeasurable space?
Thus, with a smile of joy, greet the fiery life. (AY (opens in new tab), 158)
