From such extracts from the sacred writings of the Hindus we might turn to their poets, and find the same conceptions of the emanation, manifestation, and absorption of the world illustrated. "The Infinite being is like the clear crystal, which receives into itself all the colours and emits them again, yet its transparency or purity is not thereby injured or impaired." "He is like the diamond, which absorbs the light surrounding it, and glows in the dark from the emanation thereof." In similes of a less noble nature they sought to convey their idea to the illiterate "Thou hast seen the spider spin his web, thou hast seen its excellent geometrical form, and how well adapted it is to its use; thou hast seen the play of tinted colours making it shine like a rainbow in the rays of the morning sun. From his bosom the little artificer drew forth the wonderful thread, and into his bosom, when it pleases him, he can withdraw it again. So Brahm made, and so will he absorb the world." In common the Greek and Indian asserted that being exists for the sake of thought, and hence they must be one; that the universe is a thought in the mind of God, and is unaffected by the vicissitudes of the worlds of which it is composed. In India this doctrine of emanation had reached such apparent precision that some asserted it was possible to demonstrate that the entire Brahm was not transmuted into mundane phenomena, but only a fourth part; that there occur successive emanations and absorptions, a periodicity in this respect being observed; that, in these considerations, we ought to guard ourselves from any deception arising from the visible appearance of material things, for there is reason to believe that matter is nothing more than forces filling space. Democritus raised us to the noble thought that, small as it is, a single atom may constitute a world. The doctrine of Emanation has thus a double interpretation. It sets forth the universe either as a part of the substance of God, or as an unsubstantial something proceeding from him: the former a conception more tangible and readily grasped by the mind; the latter of unapproachable sublimity, when we recall the countless beautiful and majestic forms which Nature on all sides presents. This visible world is only the shadow of God.
