Oracle of the Tarot - A Course on Tarot Divination
by Paul Foster Case
1933

From the Introduction:

TAROT divination is not fortune-telling.

The practice of fortune-telling is based on the false notion that human life is governed by luck, chance, or fate—by obscure powers at work outside the personality.

True divination rests upon the occult truth that the causes of all events in human life are really internal, proceeding from the Cause of Causes—the Universal Intelligent Energy or Life-power which is the Source, Mover and Knower behind all the phenomena of the universe.
Because this Universal Intelligent Energy is omnipresent, it must necessarily be a real presence at any given point in space. Consequently it must be the real Presence at the heart of every human personality.

That Presence is the True Self, the real I AM, the Concealed Divinity in the shrine of the temple of personality. This True self is the author of all phenomena, and its perfect knowledge includes all the details of phenomenal manifestation, past, present and future. It knows all events, and the significance of all events. Thus it knows the complete past, present and future of every human being.
