“According to the ancients doctrines, the soulless elemental spirits were evolved by the ceaselessly motion inherent in the astral light. Light is force, and the latter is produced by the will. As this will proceeds from an intelligence which cannot err, for it has nothing of the material organs of human thought in it, being the superfine pure emanation of the highest divinity itself – (Plato’s “Father”) it proceeds from the beginning of time, according to immutable laws, to evolve the elementary fabric requisite for subsequent generations of what we term human races.
All of the latter, whether belonging to this planet or to some other of the myriads in space, have their earthly bodies evolved in the matrix out of the bodies of a certain class of these elemental beings which have passed away in the invisible worlds.
In the ancient philosophy there was no missing link to be supplied by what Tyndall calls an “educated imagination”; no hiatus to be filled with volumes of materialistic speculations made necessary by the absurd attempt to solve an equation with but one set of quantities; our “ignorant” ancestors traced the law of evolution throughout the whole universe.”
