A great ancient yogi who, according to some spiritual seekers, still occasionally appears in certain areas of the Indian Himalayan Region. Legends affirm that he was born in the physical realm on November 30, 203 A.D. At the age of eleven, he joined a group of wandering ascetics. In this way he met Boganatar, a great teacher of Siddha Yoga. Boganatar sent him to another yoga master, Aghastyar. Although he was just eleven, Babaji began a strong tapas. On his forty-eighth day of fasting and meditation, Aghastyar revealed himself to Babaji and began to teach him (mainly Kriya Yoga and pranayama techniques). These practices enabled Babaji to quickly reach the state of sarupa samadhi (the condition in which the yogi transubstantiates the physical body).
