Vishuddha. The "Great Purity" center marks the fifth vortex of force which is located in the base of the throat. It has sixteen subtle "spokes" of smoky purple, which spread through the laryngeal and pharyngeal regions at the junction of the spinal column and the medulla oblongata. Known as "the doorway to the plane of eternal wisdom," it is described as "the region of ether, circular and white like a full moon."
Ralph Adamson employs a resonating crystal to illustrate this energy center, while presenting a woman's face which possesses both wonder and understanding.
