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.

The lectures are also playing continuously on Gnostic Radio:
"Wherever we direct our attention, we spend creative energy. We can save creative energy if we divide attention, if we do not become identified with things, people, and ideas. When we become identified with things, people, and ideas, we then forget our Self and lose creative energy in the most pitiful way. It is essential to know that we need to save creative energy in order to awaken the consciousness, and that the creative energy is the living potential, it is the vehicle of the consciousness, it is the instrument in order to awaken the consciousness."
