stop there, but like a lamp shedding its light far beyond the object for which it was lighted, it illumines the whole region of human life and thought, transcending its original purpose. Thus we find that truth, while investing all facts, is not a mere aggregate of facts--it surpasses them on all sides and points to the infinite reality. As in the region of knowledge so in that of consciousness, man must clearly realise some central truth which will give him an outlook over the widest possible field. And that is the object which the Upanishad has in view when it says, _Know thine own Soul_. Or, in other words, realise the one great principal of unity that there is in every man. All our egoistic impulses, our selfish desires, obscure our true vision of the soul. For they only indicate our own narrow self. When we are conscious of our soul, we perceive the inner being that transcends our ego and has its deeper affinity with the All. Children, when they begin to learn each separate letter of the alphabet, find no pleasure in it, because they miss the real purpose of the lesson; in fact, while letters claim our attention only in themselves and as isolated things, they fatigue us. They become a source of joy to us only when they combine into words and sentences and convey an idea. Likewise, our soul when detached and imprisoned within the narrow limits of a self loses its significance. For its very essence is unity. It can only find out its truth by unifying itself with others, and only then it has its joy. Man was troubled and he lived in a state of fear so long as he had not discovered the uniformity of law in nature; till then the world was alien to him. The law that he discovered is nothing but the perception of harmony that prevails between reason which is of the soul of man and the workings of the world. This is the bond of union through which man is related to the world in which he lives, and he feels an exceeding joy when he finds this out, for then he realises himself in his surroundings. To understand anything is to find in it something which is our own, and it is the discovery of ourselves outside us which makes us glad. This relation of understanding is partial, but the relation of love is complete. In love the sense of difference is obliterated and the human soul fulfils its purpose in perfection, transcending the limits of itself and reaching across the threshold of the infinite. Therefore love is the highest bliss that man can attain to, for through it alone he truly knows that he is more than himself, and that he is at one with the All.
