In 1917 in India Yogananda "began his life's work with the founding of a 'how-to-live' school for boys, where modern educational methods were combined with yoga training and instruction in spiritual ideals." In 1920 "he was invited to serve as India's delegate to an International Congress of Religious Liberals convening in Boston. His address to the Congress, on 'The Science of Religion,' was enthusiastically received." For the next several years he lectured and taught across the United States. His discourses taught of the "unity of 'the original teachings of Jesus Christ and the original Yoga taught by Bhagavan Krishna.'"
