Only the Spirit can know Him, only the Spirit can find Him; while it searches through matter it can only hope He is, but the unveiled Spirit can feel the unveiled Godhead, and by the identity of nature can know that God is, and is itself. And as this inner spiritual life more and more awakens in the religions of the world, man will know the truth of that great saying of the Christ: “The Kingdom of God is within you.” As you go down into the depths of your own being, there shall you find Deity, the conviction that God is and must be. For you can strip away from yourself everything that is not He, until only He, the one Self of all, remains. You can mutilate your body and lose your limbs, but _you_ remain. Your emotions can grow worn out and be withered, but behind your emotions _you_ still are there. Your mind may grow weaker, feebler, may become, as it were, paralysed for reasoning, and yet _you_ are there, behind the failing mind; and if you are willing to pass on into spiritual experience, to let your emotions be quieted, to let your mind be still, then in the silence of the emotions, in the tranquillity of the mind, you shall find a deeper consciousness, a deeper life, a more real individuality; and as the emotions are still and the mind is silent, in the innermost depths of the Spirit you shall find yourself and God. And then, contemplating that mighty and eternal life, you shall feel that you share it, that you are part of it, that you cannot be separated from it, and, in a great gush of experience that never again you can doubt, you shall know the reality of Deity in finding the reality of yourself. That is the ultimate conviction that nothing can shake—that the human experience that many a man has had, that for him has transformed the world; that is the sure ground of the religion of the future, that the rock on which a true faith alone can be based; and it is written, and truly written, in an ancient Hindū scripture, that the only proof of God lies in the witness of the Self. On that rock religion will base itself, fearless of all attack, of all assault. No question of chronology can move it, for every man can gain that experience for himself; no criticism and destruction of scriptures can tear this in pieces, for it is ever renewing in the perennial life of the Eternal Spirit; no churches, in failing, can shake it, for it is this that made churches, to help in its own searching; nothing outside can touch it, for it lives in the innermost heart of man. And in that, ever-opening new experiences, fuller knowledge, deeper understanding, more abounding love, and unchanging peace and bliss. Everything else may go, but this remains unchanging; and as out of this all has come, the perishing of the transient matters not, for the Eternal Source remains.
