These "opposites" are the very essence of cosmic life, the twin pillars of universal equilibrium; they have been represented in Solomon's symbolical temple—here, the Universe—by Jakin and Boaz, the white and the black columns; they are also the interlaced triangles of "Solomon's Seal," the six-pointed star, the two Old Men of the Kabbalah, the white Jehovah and the black Jehovah; Eros and Anteros, the serpents of Mercury's caduceus, the two Sphinxes of the car of Osiris, Adam and Eve, Cain and Abel, Jacob and Esau, the Chinese "Yang" and "Yin," the goblet and staff of Tarot, man and woman. All these images represent the same law.

Multiplicity, the fruit of the contraries, makes its appearance in the forms born in infinite, homogeneous Being; its goal is the goal of creation; the production, in infinite Being, of centres which are developed by evolution and finally become gods in God. These centres, or "souls," these points in the supreme Point, are divine in essence, though, so far, they have no share at all in the perfection "manifested" by God; they are all "centres," for God is a sphere, whose centre is everywhere and circumference nowhere, but they have not developed consciousness which is as yet only potential in them. Like cuttings of willow which reproduce the mother-tree, these points, veritable portions of God, are capable of germinating, growing up, and becoming "I's," self-conscious beings, intelligent and endowed with will-power, and finally gods, having developed the entire potentialities of the All by their repeated imprisonment in the series of forms that make up the visible and invisible kingdoms of nature.

Every form, i.e. aggregate of substance-force, reflects within itself one of these points of Divinity. This point is its Monad, its centre of consciousness, or soul; it is the cause which is manifested as qualities in the envelopes, and these give it the illusion of separateness for a certain period,[18] just as a soap-bubble momentarily acquires a fictitious individuality and appears separate from the atmosphere—of which it forms part—so long as its illusory envelope endures.

Thus do men imagine themselves separate from one another, when all the time their soul is nothing more than a drop of the divine Ocean, hidden momentarily in a perishable body.

The "contraries" are the anvil and the hammer which slowly forge souls by producing what might be called sensation in general, and sensation is a fertile cause of suffering each time the vehicles of consciousness receive vibrations that greatly exceed their fundamental capacity of sensation. Without sensation however—consequently without suffering—the body could neither walk,[19] nor see, nor hear, nor show any disturbance brought to bear upon it; there would exist no possible relation between the Universe and the "I," between the All and the parts, between bodies and souls; there would be no consciousness, or sensation of being, since no vibration from without would find an echo in the incarnated "centres" of life; no knowledge would be possible; man would be, as it were, in a state of nothingness; and, without suspecting it, his body might at any moment be crushed to the ground by the forces of Nature.

But these material necessities are not by any means the only ones that demand sensation; without it, one of the principal objects of evolution—the development of "Egos"—would be impossible. As an example borrowed from the domain of physical sensation, we need only call to memory a well-known experience in childhood.

All who have been at a boarding school know how heavy and fetid is the atmosphere of a dormitory in the early winter morning, when fifty boys have been breathing the same air again and again during the whole of the night. And yet, who suspected this until he had gone out for a few minutes and then returned to the bed-room? It needed the "contrary," the pure outside air, to make known the state of the atmosphere inside. The contrast produced sensation—that nauseous, suffocating impression of foul, mephitic air; suffering[20] generated knowledge of the vitiated air; as the result of this influence, the "centre of consciousness" felt itself an "I" distinct from its surroundings, and its "self-consciousness" received a slight increase.

What might be called passional sensibility—desire, emotion, impulse—is, like physical sensation, another indispensable factor in evolution; it is the special element in the development of the animal kingdom as well as of the less evolved portion of the human kingdom.

The young souls of mankind must receive the comparatively simple lessons of sensation, desire, and passion, before beginning the far more complicated study of mentality. But for desire, a host of needs could not be manifested, numberless functions would remain inactive; the body would not feed itself, and would die, were it not for hunger; danger would not be fled from, but for the instinct of self-preservation; nor without this would there be any propagation of the species. None the less is this life of sensation the source of many evils; desire and passion amongst human beings create terrible misery, fill prisons and hospitals, and are at the root of all kinds of moral suffering. In its turn, intelligence—that sensation so characteristic of the human state—is both an indispensable necessity and the most fertile source of evil, so long as it has not experienced a yearning for that inner "divinity," deep in the heart of man, which calls to it. A powerful lever of progress, it might convert this earth into a paradise, whereas it is the weapon which the strong, in their egoism, use to crush the feeble, a terrible weapon which either creates or intensifies all the evils under which the people writhe in despair. Once it becomes the instrument of a regenerate humanity, that is to say, when men have become compassionate, loving, and devoted, then the social question will cease to exist, and the old instrument of torture will become a pledge of general happiness.

Even spiritual sensibility is a cause of suffering to some noble souls who have developed it, for however deep the joy of loving and giving oneself, intense too is the pain of witnessing the cruel drama of life, that fratricidal struggle in which passion strikes without mercy, whilst illusion and ignorance deal blows even more terrible, for into the wounds they make they instil the poison of revolt and despair.
