Thelema considers any action which is not directed toward the discovery and accomplishment of the True Will to be "black magic". This includes acts of interference with any other individual's lawful exercise of their right to discover and accomplish their own True Will. Thelemic doctrine holds that the disharmony and imbalance created by such actions results in a compensatory, equilibrating response from the universe; a doctrine similar to that of the Eastern conception of "Karma". Thelema has no direct parallel to the Judaeo-Christian concept of the devil or Satan; however, a pseudo-personification of confusion, distraction, illusion and egotistical ignorance is referred to by the name " Choronzon ".

Thelema incorporates the idea of the cyclic evolution of Cultural Consciousness as well as of Personal Consciousness. History is considered to be divided into a series of " Aeons ", each with its own dominant concept of divinity and its own "formula" of redemption and advancement. The current Aeon is termed the Aeon of Horus. The previous Aeon was that of Osiris, and previous to that was the Aeon of Isis. The neolithic Aeon of Isis is considered to have been dominated by the Maternal idea of divinity, and its formula involved devotion to Mother Earth in return for the nourishment and shelter She provided. The Classical/Medieval Aeon of Osiris is considered to have been dominated by the Paternal Principle, and its formula was that of self-sacrifice and submission to the Father God.

The modern Aeon of Horus is considered to be dominated by the Principle of the Child, the sovereign individual; and its formula is that of growth, in consciousness and love, toward self-realization
