To the question so often asked as to why we are here, why man must pass through experiences, some of which seem heartrending, the answer is plain: Without some such experience there could be no Life, there could be no Love, and there could be no Wisdom.

We cannot perceive the light, except we have had experience with varying degrees of its intensity; and if we have had some experience with darkness, we the more readily appreciate the light. We can have no knowledge of the good, unless we have had some experience with that which is less good; and if we have had some experience with that which we call evil, the good is the more appreciated. Sweetness, to the sense of taste, is only perceived by comparison with things less sweet. It takes the sour, such as lemon, to bring out in proper contrast the sweetness of honey. In fact, the wider the range of experience the clearer the perception of qualities and values. Without some such experiences with form as we are familiar with there would be no life, no consciousness, no knowledge, no love. It is impossible to imagine how life, wisdom, and love could be developed, or could exist, without some such chain of experiences as those with which we are familiar.

As to the why of existence itself, that is, the why of the potentiality manifesting through the universe of form, we are not called upon to explain it. We cannot conceive of a condition in which existence is lacking, nor have we had any experience that suggests such a condition ever was possible. It is quite enough, then, for the human mind to attempt to explain how existence acts and is conditioned, without attempting to commence from nothingness, which is logically impossible, and show how all that exists was derived from this unthinkable, impossible, abstraction. But if we commence with a potentiality, such as the ego undoubtedly is, it is not difficult to trace the steps by which the soul must have gradually developed until it finally functions through the body of man.

Therefore, if the soul is to develop power; which depends upon its strength to attract and repel, upon Love; and if it is to develop knowledge, and not remain semiconscious, it must have experiences of as wide contrast and of as great variety as possible. Contrast means strong impressions and strong desires. Variety means discrimination and fine shades of feeling. A creature without these is not alive in the full sense that man is alive.

The greatest contrast of which we know is that between spirit, or still finer substance, and matter. And the greatest variety of which we know is the countless forms on the physical, the astral, and the spiritual planes.

If, therefore, the soul is to develop its powers, there is no means that we can imagine which would be so effective as its association with the various forms of the physical, the astral, and the spiritual worlds; for these forms offer the widest possible contrast of which it is possible to conceive. They, therefore, offer the greatest opportunity to develop the attributes of attraction and repulsion; the greatest opportunity to develop feeling, to develop that which becomes Love.

And if the soul is to develop discrimination, there is no means that we can imagine which would be so effective as its association with the various forms of the physical, the astral, and the spiritual worlds; for these forms offer the widest possible variety of which it is possible to conceive. They, therefore, offer the greatest opportunity to develop the attributes of perception and comparison; the greatest opportunity to develop knowledge; to develop that which becomes Wisdom.

That the soul may acquire Self-Consciousness it must attain Wisdom. Life, however, depends also upon love; for love is the power that attracts and holds together whatever form the soul occupies. If the soul is to be immortal it must develop sufficient love, sufficient attractive power, to build such forms as are necessary for its imperishable existence. Love and Wisdom are the essential factors of Immortal Life.

Because there is no conceivable way by which the soul can acquire love and wisdom except through varied experiences in form, the cycle through which the soul passes, from spirit to matter and from matter back to spirit; living in countless forms in each of the three realms; is called by initiates, “The Cycle of Necessity.” That is, this cycle of experiences in various forms is a necessity if the soul is to acquire the love and wisdom which alone make possible Self-Conscious Immortality. The mission of the soul, therefore, is to acquire Love and Wisdom to the end that Self-Conscious Immortality may be attained.
