Throughout the year, we are continually influenced by subtle energies in nature, and they change as the Earth, Moon, and Sun move. During June and July, the constellation Cancer has a strong influence, so during this time we take advantage of that to prepare our physical bodies for practical priesthood.
"These exercises of preparing the body are practiced throughout our entire lifetime. When the theurgist has his body well prepared, he can make the sidereal gods visible in the physical plane. This requires patience and perseverance, because nothing is just handed to us. Everything has the price of struggle and sacrifice. The forces that descend from heaven, on arriving at our thymus gland, meet the forces that ascend through our organism from the earth, and there, in the thymus gland, the two triangles of the superior and inferior forces interlace to form the seal of Solomon.
"Sit down and imagine this marvelous encounter of the cosmic forces forming the seal of Solomon at the thymus gland and, while submerged within profound inner meditation, pray to your Innermost to enter the sidereal temple of the principal star of Cancer, to bring thee the principal hierarchies of that constellation, so that they may awaken your inner powers and give that gland a treatment. Vocalize the letter “A” [as in "father"] for one hour daily." —Practical Astrology by Samael Aun Weor
"In these studies of Kabbalah, we need to be practical; there are authors who write marvels, but when one looks at them, one realizes that they have not lived what they have written; they did not experience it in themselves, and that is why they are mistaken. I understand that one must write what one has directly experienced by oneself. I have proceeded in this way for my part."
