About Sri Yukteswar Giri
Known as Priyanath Karar or ‘Karar Swami’ in his pre-monastic days, he was the chief monastic disciple of the pioneer, Shyamacharan Lahiri. For his extraordinary wisdom and erudition, he was also known as ‘Jnanavatar’ or ‘the incarnation of wisdom’. On the directions of Mahavatar Babaji, he wrote ‘Kaivalya Darshan’ or ‘The Holy Science – a treatise’ showing parallels between the ancient Hindu and Christian scriptures. An Astrologer and Astronomer par excellence, he discovered the correct method of calculating the World Ages and the cyclical order of evolution. As a fully realized Kriya Yogi, he established the Karar Ashram at Puri for dissemination of the ancient teachings of which he was the founder, President and Sadhusabhapati. Was instrumental in spreading the message of Kriya across the Globe through his disciple, Paramhansa Yogananda.
