Fom time immemorial, India produced many great saints and sages, who demonstrated through their lives, the characteristics of a perfect man. The light emitting from them cleared the path for many struggling souls and showered the nectar of peace and happiness on them. The study of these great lives and their teachings will certainly be a source of inspiration to every one.
Anything that is secret and mysterious in these systems of yoga should be at once rejected. The best guide in life is strength. In religion, as in all other matters, discard everything that weakens you, have nothing to do with it.
-Swami Vivekananda
