The very thought that infinite space cannot be understood, is itself a proof that the mind unconsciously realises the precise nature of such infinity, in attributing to it at once the all-comprehensiveness from which there is no escape, in which all dimensions exist, and by virtue of which all other conceptions become possible; since this infinite space contains in itself all dimensions of existence—­transitory, real and potential; and if the capacity of the mind is co-extensive with the capacity of infinite space, since it feels itself undoubtedly capable of grasping any limited idea contained in any portion of the illimitable whole, it follows that the mind is of itself as infinite as the space in which all created things have their transitory form of being, and in which all uncreated truths exist eternally.  The mind is aware of infinity by that true sort of knowledge which is an intimate conviction not dependent upon the operation of the senses.

Gradually, too, as Zoroaster fixed his intuition upon the first main principle of all possible knowledge, he became aware of the chief cause—­of the universal principal of vivifying essence, which pervades all things, and in which arises motion as the original generator of transitory being.  The great law of division became clear to him—­the separation for a time of the universal agent into two parts, by the separation and reuniting of which comes light and heat and the hidden force of life, and the prime rules of attractive action; all things that are accounted material.  He saw the division of darkness and light, and how all things that are in the darkness are reflected in the light; and how the light which we call light is in reality darkness made visible, whereas the true light is not visible to the eyes that are darkened by the gross veil of transitory being.  And as from the night of earth, his eyes were gradually opened to the astral day, he knew that the forms that move and have being in the night are perishable and utterly unreal; whereas the purer being which is reflected in the real light is true and endures for ever.

Then, by his knowledge and power, and by the light that was in him, he divided the portion of the universal agent that was in the cave where he dwelt into two portions, and caused them to reunite in the midst upon the stone that was there; and the flame burned silently and without heat upon his altar, day and night, without intermission; and by the division of the power within him, he could divide the power also that was latent in other transitory beings, according to those laws which, being eternal, are manifested in things not eternal, but perishable.

And further, he meditated upon the seven parts of man, and upon their separation, and upon the difference of their nature.

For the first element of man is perishable matter.

And the second element of man is the portion of the universal agent which gives him life.
