In the “Arcane Lessons,” you have seen that the individual is but a centre of consciousness and force in the great life principle, cosmic will, or spirit. As Aphorism XII has informed you: “There is but One Life and not Many Lives. Separateness is but relative and partial—illusory—the creative fiction of the Cosmos…. In the Cosmic Will there is but One Life in which, and by which, is manifested the Many.”

Neville Goddard was a philosopher, spiritual teacher, and author who focused on the power of the mind. His teachings are based on New Thought spirituality, which combines principles of various religions and metaphysical ideas.

The Kybalion is a book originally published in 1908 by "Three Initiates" (often identified as the New Thought pioneer William Walker Atkinson, 1862–1932) that purports to convey the teachings of Hermes Trismegistus. While it shares with ancient and medieval Hermetic texts a number of traits such as philosophical mentalism, the concept of 'as above, so below', and the idea that everything consists of gendered polar opposites, as a whole it is more indebted to the ideas of modern occultist authors, especially those of the New Thought movement to which Atkinson belonged.

Drawing on a breadth of scientific knowledge and a deep understanding of the world's spiritual traditions, The Pineal Gland: The Eye of God is essential listening for anyone with an interest in the occult.

Writing as Magus Incognito William Walker Atkinson explores the Seven Aphorism of the Rosicrucian doctrine. These traditions emphasize the pursuit of spiritual enlightenment and personal transformation through the understanding of hidden truths and the transmutation of the self. He describes the path of the Rosicrucian initiate: a journey of self-discovery, spiritual development, and the attainment of higher states of consciousness.
