After a leg injury forced him to leave basketball in the fall of 1980, Maravich became a recluse for two years. Through it all, Maravich said he was searching "for life." He tried the practices of yoga and Hinduism, read Trappist monk Thomas Merton's The Seven Storey Mountain and took an interest in the field of ufology, the study of unidentified flying objects. He also explored vegetarianism and macrobiotics. In 1982, he became a Christian and began traveling the country sharing his new found faith in Jesus Christ.
A few years prior to his death, Maravich said, "I want to be remembered as a Christian, a person that serves Him to the utmost. Not as a basketball player."
