"Gnosis is the common Greek noun for knowledge (in the nominative case \u03B3\u03BD\u1FF6\u03C3\u03B9\u03C2 f.). In Christian, Islamic, or Jewish mysticism, mystery religions and Gnosticism gnosis generally signifies a spiritual knowledge or \"religion of knowledge\", in the sense of mystical enlightenment or \"insight\". Gnosis taught a deliverance of man from the constraints of earthly existence through insight into an essential relationship, as soul or spirit, with a supramundane place of freedom."@en . . . . .
