Joseph Smith visited me a great deal after his death, and taught me many important principles. . . . Among other things, he told me to get the Spirit of God; that all of us needed it. . . . He said, "I want you to teach the people to get the Spirit of God. You cannot build up the Kingdom of God without that." . . . But how is it with the Holy Ghost? The Holy Ghost does not leave me if I do my duty. It does not leave any man who does his duty.
