Humanity is terrified of everything “supernatural,” forgetting that nothing can be supernatural—that is, beyond the real. Therefore, strongly insist that Agni Yoga and the Teaching of the Heart cannot contain anything supernatural. Be especially cautious with people under thirty, since they are still at an age when not all of the centers can function without harm to the heart. It is essential that you make clear that Our Yoga includes no coercive magic and would never generate chaos. You need to light the fires of podvig in the young, to kindle heroic achievements that will transform their essence and, imperceptibly to them, prepare their hearts for future perfectment.
