Aleister Crowley engaged in occultism.
Crowley's thought was not always cohesive, and was influenced by a variety of sources, ranging from eastern religious movements and practices like Hindu yoga and Buddhism, scientific naturalism, and various currents within Western esotericism, among them ceremonial magic, alchemy, astrology, Rosicrucianism, Kabbalah, and the Tarot
 Crowley has remained a highly influential figure over Western esotericism and the counterculture of the 1960s, and continues to be considered a prophet in Thelema
