Included for reference are the actual Sanskrit texts for each hymn. The "Doctrine of the Mystics" reveals the underlying philosophical, psychological and spiritual truths experienced by the sages. This book is for the seeker, the yogi, the sage as well as the philosopher or student of comparative religion. It can clarify the teachings of ancient India and at the same time, can unlock the door and open the aspirant to the experience of that reality that moved the ancient sages to high poetic expression.
