Applewhite and Nettles opened a bookstore known as the Christian Arts Center, which carried books from a variety of spiritual backgrounds. They also launched a venture known as Know Place to teach classes on theosophy and mysticism. The pair closed these businesses a short time later. In February 1973, Applewhite and Nettles resolved to travel to teach others about their beliefs and drove throughout the Western U.S.; Lifton describes their travels as a "restless, intense, often confused, peripatetic spiritual journey". While traveling, they had little money and occasionally resorted to selling their blood or working odd jobs for much-needed funds. The pair subsisted solely on bread rolls at times, often camped out, and sometimes did not pay their lodging bills. One of their friends from Houston corresponded with them and accepted their teachings. They visited her in May 1974, and she became their first convert.
