The Universal Meaning of the Kabbalah1973
All creation is an illusory projection of the transcendental aspects of God in the mirror of its immanence. …
Illusion is not, nor can it be, in itself, a mere nothing. The illusion is a ‘blend’ of the real and the ephemeral, or -dictated with kabbalistic terminology – of ‘light’ and ‘darkness’.
