About 1903 Mr. Jeffery met Dr. Charles Brodie Patterson, a member of the Royal Society of Arts, Letters, and Sciences of Great Britain, who was doing healing work in New York City and giving a series of lectures on what then was the new subject of "metaphvsics." Dr. Patterson was so impressed by Mr. Jeffery that he asked him to join him in the work. As Dr. Patterson's lectures became more and more time consuming, the ministry fell more and more to Mr. Jeffery; and when Dr. Patterson returned to England Mr. Jeffery took over his healing ministry in New York and opened a second office in Philadelphia. Mr.Jeffery did specialized work in philosophy at Harvard University and Columbia; he also studied metaphysics with Dr. James Porter Mills of London. About 1905 he met Mrs. Emma Curtis Hopkins, the "teacher of teachers." He worked with her in producing her classic "High Mysticism"; and about 1910 and 1911 he gave a series of lectures in England and Europe on "High Mysticism."
