The Rosicrucian Mysteries is a classic religious studies text by Max Heindel that features the following excerpt: Before entering upon an explanation of the teachings of the Rosicrucians, it may be well to say a word about them and about the place they hold in the evolution of humanity. For reasons to be given later these teachings advocate the dualistic view; they hold that man is a spirit enfolding all the powers of God as the seed enfolds the plant, and that these powers are being slowly unfolded by a series of existences in a gradually improving earthy body; also that this process of development has been performed under the guidance of exalted beings who are yet ordering our steps, though in a decreasing measure, as we gradually acquire intellect and will. These exalted Beings, though unseen to the physical eyes, are nevertheless potent factors in all affairs of life, and give to the various groups of humanity lessons which will most efficiently promote the growth of their spiritual powers.
