As we find that somehow or other, by the laws of our mental constitution, we have to associate our ideas of infinity with the image of the blue sky, or of the sea, so we naturally connect our idea of holiness with the image of a church, a mosque, or a cross. The Hindus have associated the idea of holiness, purity, truth, omnipresence, and such other ideas with different images and forms. But with this difference that while some people devote their whole lives to their idol of a church and never rise higher, because with them religion means an intellectual assent to certain doctrines and doing good to their fellows, the whole religion of the Hindu is centred in realisation. Man is to become divine by realising the divine. Idols or temples or churches or books are only the supports, the helps, of his spiritual childhood: but on and on he must progress. He must not stop anywhere. "External worship, material worship," say the scriptures, "is the lowest stage; struggling to rise high, mental prayer is the next stage, but the highest stage is when the Lord has been realised." Mark, the same earnest man who is kneeling before the idol tells you, "Him the Sun cannot express, nor the moon, nor the stars, the lightning cannot express Him, nor what we speak of as fire; through Him they shine." But he does not abuse any one's idol or call its worship sin. He recognises in it a necessary stage of life. "The child is father of the man." Would it be right for an old man to say that childhood is a sin or youth a sin?
