The word cult comes from Latin cultus, "worship," from past participle of colere, "to cultivate." This short course explains what a cult is, and discusses many types of cults: Christian, Muslim, Buddhist, Gnostic, etc., and how we worship according to our inner psychological and spiritual state. Every spiritual person is engaged in worship (cult), but our psychological state determines whether that worship results in benefit or harm.
This short course was originally given live and unscripted on Gnostic Radio.
