Learn about your pineal gland and your third eye!
Sufficient similarity exists between the CHiram and the Kundalini of Hindu mysticism to warrant the assumption that CHiram may be considered a symbol also of the Spirit Fire moving through the sixth ventricle of the spinal column. The exact science of human regeneration is the Lost Key of Masonry, for when the Spirit Fire is lifted up through the thirty-three degrees, or segments of the spinal column, and enters into the domed chamber of the human skull, it finally passes into the pituitary body (Isis), where it invokes Ra (the pineal gland) and demands the Sacred Name. Operative Masonry, in the fullest meaning of that term, signifies the process by which the Eye of Horus is opened. E. A. Wallis Budge has noted that in some of the papyri illustrating the entrance of the souls of the dead into the judgment hall of Osiris the deceased person has a pine cone attached to the crown of his head. The Greek mystics also carried a symbolic staff, the upper end being in the form of a pine cone, which was called the thyrsus of Bacchus. In the human brain there is a tiny gland called the pineal body, which is the sacred eye of the ancients, and corresponds to the third eye of the Cyclops. Little is known concerning the function of the pineal body, which Descartes suggested (more wisely than he knew) might be the abode of the spirit of man. As its name signifies, the pineal gland is the sacred pine cone in man – the eye single, which cannot be opened until CHiram (the Spirit Fire) is raised through the sacred seals which are called the Seven Churches in Asia.” -Manly P.

"The Thymus chakra responds to all sounds made by you, and any with which you are in contact. There is much sensitivity in the area of the Thymus chakra because of the bony structure that overlays it. When you sing or shout, pray or chant, or listen to music, whether it be recorded or played live by many musicians, the Thymus chakra is stimulated. From here is directed renewed energy as a result of the sound.
