Pituitary Gland

There are seven cavities in the Brain which during life are empty, in the ordinary sense of the word. In reality, they are filled with Âkâúa, each cavity having its own color, according to the state of Consciousness in which you are. (The colors are only visible, of course, to the purified vision.) These cavities are called in Occultism the “Seven Harmonies,” the scale of the Divine Harmonies, and it is in these that visions must be reflected, if they are to remain in the Brain-memory. These are the parts of the Brain which receive impressions from the Heart, and enable the memory of the Heart to be impressed on the memory of the Brain.

The fourth of these cavities is the Pituitary Body, which corresponds with Manas-AntaskaraŠa, the bridge to the Higher Intelligence; it contains various essences. 697

The Pituitary Body is the organ per se of the psychic plane. Pure psychic vision* is caused by the molecular motion of this body, which is directly connected with the optic nerve, and thus affects the sight, and gives rise to hallucinations. Its motion may readily cause flashes of light, seen within the head, similar to those that may be obtained on pressing the eyeballs, and so causing molecular motion in the optic nerve. When molecular action is set up in the Pituitary Body these flashes are seen, and further action gives psychic vision, as similar motion in the Pineal Gland gives Spiritual Clairvoyance. Drunkenness and fever cause disorderly motion in the Pituitary Body, and so produce illusions of sight, visions, hallucinations. This body is sometimes so affected by drunkenness that it is paralyzed, and the strict forbiddance of alcoholic liquids to all students of Occultism turns on this effect which alcohol produces on the Pituitary Body and Pineal. 698
