Chapter II: The Nature of Humanity

This work leads on to ever higher levels of human nature. Through it man evolves new members of his being, which lie—as yet unmanifest—behind what is manifest in him. Moreover, it is not only the soul over which a man can attain mastery by working upon it from the Ego, till from the manifest within the soul the unmanifest springs forth. He can extend this work still further, carrying it over to the astral body. As he does so, the Ego gains power over the astral body, entering into union with its hidden nature. The astral body thus mastered and transformed by the I may be called the ‘Spirit-Self.’ (This is identical with what is called, in connection with Oriental wisdom, ‘Manas.’) In the Spirit-Self we have therefore a higher member of man's nature, one which is already present in him—germinally, as it were—and comes forth ever more and more as he continues to work upon himself.
