I said, "If consideration for our individuality could sway nature from her path, then it would be the individuals who would suffer most." But he persisted in his doubt, saying that there was this fact which could not be ignored--the feeling that I am. The "I" in us seeks for a relation which is individual to it. I replied that the relation of the "I" is with something which is "not-I." So we must have a medium which is common to both, and we must be absolutely certain that it is the same to the "I" as it is to the "not-I." This is what needs repeating here. We have to keep in mind that our individuality by its nature is impelled to seek for the universal. Our body can only die if it tries to eat its own substance, and our eye loses the meaning of its function if it can only see itself. Just as we find that the stronger the imagination the less is it merely imaginary and the more is it in harmony with truth, so we see the more vigorous our individuality the more does it widen towards the universal. For the greatness of a personality is not in itself but in its content, which is universal, just as the depth of a lake is judged not by the size of its cavity but by the depth of its water. So, if it is a truth that the yearning of our nature is for reality, and that our personality cannot be happy with a fantastic universe of its own creation, then it is clearly best for it that our will can only deal with things by following their law, and cannot do with them just as it pleases. This unyielding sureness of reality sometimes crosses our will, and very often leads us to disaster, just as the firmness of the earth invariably hurts the falling child who is learning to walk. Nevertheless it is the same firmness that hurts him which makes his walking possible. Once, while passing under a bridge, the mast of my boat got stuck in one of its girders. If only for a moment the mast would have bent an inch or two, or the bridge raised its back like a yawning cat, or the river given in, it would have been all right with me. But they took no notice of my helplessness. That is the very reason why I could make use of the river, and sail upon it with the help of the mast, and that is why, when its current was inconvenient, I could rely upon the bridge. Things are what they are, and we have to know them if we would deal with them, and knowledge of them is possible because our wish is not their law. This knowledge is a joy to us, for the knowledge is one of the channels of our relation with the things outside us; it is making them our own, and thus widening the limit of our self.
