Mahavatar Babaji’s given name and date of birth are not known, so those who met him during that period all called him by the title first given to him by Lahiri Mahasaya. "Mahavatar" means "great avatar", and "Babaji" simply means "revered father". Some of the encounters included two or more witnesses—discussions between those who met Mahavatar Babaji indicate that they all met the same person.
Meetings with Mahavatar Babaji , 1861-1966
Lahiri Mahasaya
The first reported encounter with Mahavatar Babaji was in 1861, when Lahiri Mahasaya was posted to Ranikhet in his work as an accountant for the British government. One day while walking in the hills of Dunagiri above Ranikhet, he heard a voice calling his name. Following the voice up the mountain, he met a “tall, divinely radiant sadhu.” He was amazed to find that the sadhu knew his name. This sadhu was Mahavatar Babaji.Mahavatar Babaji told Lahiri Mahasaya that he was his guru from the past, then initiated him into Kriya Yoga and instructed Lahiri to initiate others. Lahiri wanted to remain with Mahavatar Babaji, who told him instead that he must return to the world to teach Kriya Yoga and that “Kriya Yoga sadhana would spread through the people of the world through his (Lahiri’s) presence in the world.”
