The Ancient Mystical Order Rosae Crucis, also known as the Rosicrucian Order, AMORC, is a worldwide cultural, educational, and philosophical organization that is perpetuating the profound and practical teachings of the Rosicrucians. Today, in honor of the birthday of the esteemed Harvey Spencer Lewis, who founded the Rosicrucian Order in 1915, we will present excerpts on “Mastership and Perfection” from the book “The Sanctuary of Self,” written by his son, Ralph M. Lewis. "Mastership is not only the ability to advocate a way or procedure by which something is to be done. It also consists of the personal power of accomplishment. …Mystic mastership or mastery of mysticism is therefore the finding of the God Power within oneself. Its practical application consists of learning the usage, to the fullest extent, of these powers and forces with which the Cosmic has endowed us."
