“When Man fell and assumed his present physical form, the West [Tharmas] went outward and became the Circumference, or body; the South [Urizen] ascended and took dominion as the Zenith, or head; the North [Urthona] sank out of sight and became the Nadir, or subconscious; while the East [Luvah] turned inward and became “the Center, unapproachable for ever,” or the heart. When they were thus materialized, the Four established communication with the outer world by the Four Senses: “the Eyes are the South, and the Nostrils are the East, and the Tongue is the West, and the Ear is the North” (J 12:54–60).”
