“SPACE is, in reality, the container and the body of the Universe with its seven principles. It is a body of limitless extent, whose PRINCIPLES, in Occult phraseology – each being in its turn a septenary – manifest in our phenomenal world only the grossest fabric of their subdivisions.
“No one has ever seen the Elements in their fullness”, the Doctrine teaches. We have to search for our Wisdom in the original expressions of the primeval people and in their synonyms.
They made of Ether, the fifth Element, the synthesis of the other four; for the Aether of the Greek philosophers is not its dregs – of which indeed they knew more than science does now – which are rightly enough supposed to act as an agent for many forces that manifest on Earth.
Their Aether was the Akasa of the Hindus; the Ether accepted by physics is but one of its subdivisions, on our plane – the Astral Light of the Kabbalists with all its evil as well as good effects.
On account of the Essence of Aether, or the unseen Space, being held divine as the supposed veil of Deity, it was regarded as the medium between this life and the next one.
The ancients considered that when the directing active “Intelligences” (the gods) retired from any portion of Ether in our Space – the four realms which they superintend – then that particular place was left in the possession of evil, so-called by reason of the absence of the Good from it.
According to Hindu teaching, Deity in the shape of Aether (Akasa) pervades all things; and it was called therefore by the theurgists “the living fire”, the “Spirit of Light”, and sometimes Magnes.
It was the highest Deity itself which, according to Plato, built the Universe in the geometrical form of the Dodecahedron; and its “first begotten” was born of Chaos and Primordial Light (the Central Sun).
This “First-Born”, however, was only the aggregate of the Host of the “Builders”, and first constructive Forces, who are called in ancient cosmogonies the Ancients (born of the Deep, or Chaos) and the “First Point”. He is the Tetragrammaton, so-called, at the head of the seven lower sephiroth.
This was the belief of the Chaldeans. “These Chaldeans”, writes Philo, “were of opinion that the Kosmos, among the things that exist(?) is a single point, either being itself God (Theos) or that in it is God, comprehending the soul of all things.”
