Boganathar was the Siddha guru of Kriya Babaji Nagaraj, the famed Himalayan master, of whom much has been written. Boganathar lived an extremely long life through the use of alchemical rejuvenation formulae and special breathing techniques. He traveled all over the world, chronicled the lives of Siddhas much older than himself, and provided his disciples an illumined path to Self-realization and integral transformation of human nature into divinity. His astounding life provides a shining example of our human potential. The present work provides a biography of Boganathar, as we can glean it from his writings alone, as well as introductory chapters on the Siddha tradition and Kundalini Yoga. The present work also provides a translation and commentary of about seventy-five selected poems, which serious students of all traditions of Kundalini Yoga and Tantra will find illuminating. By meditating upon the verses, the reader will be able to draw much inspiration.The present work provides a word-by-word translation, with alternative meanings, as well as a literal translation, and finally an interpretative translation, to balance the need for precision and understanding and to facilitate a deeper meditative approach to the various layers of meaning of each verse.
