An Essay on the Fundamental Principles of Operative Occultism, by Manly P. Hall. 1951 stapled softcover. 70 pages, very nice condition.

This illustrated essay was written to explain the symbolism and iconography of three oil paintings by the artist Mihran K. Serailian: 'The Opening of the Third Eye,' 'The Seven Spinal Chakras,' and 'A Synthetic Emblematic Cross.' The question is asked, 'What must I do to unfold the divine powers latent within myself? While it is not possible to give a direct answer to this question, we may cast some light on the subject by defining the fundamental principles upon which the Mystery Schools of all ages were established as institutions of philosophic, ethical, and religious culture. The Schools of the Mysteries are composed of illumined men and women who have been accepted into the company of the Immortals. To reach this exalted position requires an almost inconceivable amount of preparatory labor; for if man would associate with these advanced types of humanity, he must raise himself to their level.

Manly Palmer Hall (1901 – 1990) was an American writer, lecturer, astrologer, and mystic. Over his 70-year career he gave thousands of lectures and published over 150 volumes, of which the best known is The Secret Teachings of All Ages (1928). In 1934 he founded the Philosophical Research Society in Los Angeles.
