A Master who has completed the Second Mountain, thereby eliminating the entirety of their defects, and has resurrected his or her physical body. This type of master has no ego (pride, lust, anger, etc), but still needs to work a lot in order to gain the right to enter into the Absolute.
"Every resurrected master has Solar Bodies, but does not have Lunar Bodies. The resurrected masters have powers over fire, air, water and the earth. Resurrected masters can transmute physical lead into physical gold. The resurrected masters govern life and death. They can conserve the physical body for millions of years. They know the quadrature of the circle and the perpetual movement. They have the universal medicine, and speak the very pure language of the Divine Tongue which, like a golden river, flows delightfully through the thick, sunny jungle." - Samael Aun Weor, The Esoteric Treatise of Hermetic Astrology
"The [number of] resurrected masters can be counted on the fingers of the hands. [...] Hermes, Cagliostro, Paracelsus, Nicholas Flamel, Quetzalcoatl, St. Germain, Babaji, etc., preserved their physical bodies for thousands, and even millions of years, without death harming them. They are resurrected masters." - Samael Aun Weor, Alchemy and Kabbalah
