In 1920, while in meditation one day at his Ranchi school, Yogananda received a vision: faces of a multitude of Americans passed before his mind's eye, intimating to him that he would soon go to America. After giving charge of the school over to its faculty (and eventually to his brother disciple Swami Satyananda), he left for Calcutta; the following day he received an invitation from the American Unitarian Association to serve as India's delegate to an International Congress of Religious Liberals convening that year in Boston. Seeking out his guru's advice, Sri Yukteswar advised him to go; later, while in deep prayer in his room, he received a surprise visit from Mahavatar Babaji, the Great Guru of his lineage, who told him directly that he was the one chosen by the Masters to spread Kriya Yoga to the West. Reassured and uplifted, Yogananda soon afterwards accepted the offer to go to Boston. This account became a standard feature of his lectures.
