To man, the Essence of God is incomprehensible, so also are
the worlds beyond this, and their condition. It is given to man to obtain
knowledge, to attain to great spiritual perfection, to discover hidden truths
and to manifest even the attributes of God; but still man cannot comprehend the
Essence of God. Where the ever-widening circle of man’s knowledge meets the
spiritual world a Manifestation of God is sent to mirror forth His splendour.
