Thus our mental action produces a corresponding re-action in the mind of the Spirit, which in its turn reproduces itself as a special manifestation of the Life of the Spirit in us; and so long as this circulation between the individual spirit and the Great Spirit is kept up, the individual life will be maintained, and will also strengthen as the circulation continues, for the reason that the Spirit, as the Original Creative Power, is a Multiplying Force, and the current sent into it is returned multiplied, just as in telegraphy the feeble current received from a distance at the end of a long line operates to start a powerful battery in the receiving office, which so multiplies the force as to give out a clear message, which but for the multiplication of the original movement could not have been done.

Something like this we may picture the multiplying tendency of the Originating Mind, and consequently the longer the circulation between it and the individual mind goes on the stronger the latter becomes; and this process growing habitual becomes at last automatic, thus producing an endless flow of Life continually expanding in intelligence, love, power and joy.
But we must note carefully that all this can only proceed from the individual's recognition that his own powers are a derivative from the All-originating Spirit, and that they can continue to be used constructively only so long as they are employed in harmony with the inherent Forward Movement of the Spirit.

Therefore to insure this eternally flowing stream of Life from the Universal Spirit into the individual there must be _no inversion_ in the individual's presentation of himself to the Originating Power: for through the very same Law by which we seek Life--the Life namely, of reciprocal action and re-action--every inversion we bring with us in presenting ourselves to the Spirit is bound to be faithfully reproduced in a corresponding re-action, thus adulterating the stream of Pure Life, and rendering it less life-giving in proportion to the extent to which we invert the action of the Life-principle; so that in extreme cases the stream flowing through and from the individual may be rendered absolutely poisonous and deadly, and the more so the greater his recognition of his own personal power to employ spiritual forces.
The existence of these negative possibilities in the spiritual world should never be overlooked, and therefore the essential condition for receiving the Perfect Fulness of Life is that we should present ourselves before the Eternal Spirit free from every trace of inversion.

To do this means to present ourselves in the likeness of the Divine Ideal; and in this self-presentation the initiative, so far as the individual is consciously concerned, must necessarily be taken by himself.

He is to project into the Eternal Mind the conception of himself as identical with its Eternal Ideal; and if he can do this, then by the Law of the Creative Process a return current will flow from the Eternal Mind reproducing this image in the individual with a continually growing power.
