“From the standpoint of the highest metaphysics, the whole Universe, gods included, is an illusion; but the illusion of him who is in himself an illusion differs on every plane of consciousness;
and we have no more right to dogmatize about the possible nature of the perceptive faculties of the Ego on, say, the sixth plane, than we have to identify our perceptions with, or make them a standard for , those of an ant, in its mode of consciousness.
What, then, is the “primordial Substance”, that mysterious object of which Alchemy was ever talking, and which became the subject of philosophical speculation in every age?
What can it be finally, even in its phenomenal pre-differentiation? Even that is ALL in manifested Nature and – nothing to our senses.
It is mentioned under various names in every Cosmogony, referred to in every philosophy, and shown to be, to this day, the ever-eluding PROTEUS in Nature.
We touch and do not feel it; we look at it without seeing it; we breathe it and do not perceive it; we hear and smell it without the smallest cognition that it is there;
for it is in every molecule of that which in our illusion and ignorance we regard as Matter in any of its states, or conceive as a feeling, a thought, an emotion.
In short, it is the “upadhi”, or vehicle, of every possible phenomenon, whether, physical, mental, or psychic.
In the opening sentences of Genesis, as in the Chaldean Cosmogony, in the Puranas of India, and in the Book of the Dead of Egypt, it opens everywhere the cycle of manifestation.
It is termed “Chaos”, and the face of the waters, incubated by the Spirit proceeding from the Unknown, under whatever name.”
