Gabriel and Hope's retreat
The retreat of Archangel Gabriel and Hope is located in the etheric plane between Sacramento and Mount Shasta and is extended for the protection of San Francisco through the retreat of the Goddess of Purity.
The retreats of the archangels have a vast energy field of concentration, and the presence of these retreats accounts for the great purity of this area of Northern California. The retreat was present long before the sinking of Lemuria and was destined to show forth the pristine pattern of purity for the entire continent of Mu and for the Western Hemisphere.
Mark L. Prophet and Elizabeth Clare Prophet, The Masters and Their Retreats, s.v. “Gabriel and Hope’s Retreat.”
