Maya
Maya [Sanskrit Lit. “illusion,” “deception,” “appearance”]: Something created or fabricated, not ultimately real; the impermanent phenomenal world viewed as reality; the principle of relativity and duality by which the one Reality appears as the manifold universe.
The ascended masters teach that maya is the veil of misqualified energy that man imposes upon Matter through his misuse of the sacred fire.
