“Sun-worship and pure forms of nature worship were, in their day, noble religions, highly allegorical but full of profound truth and knowledge.”

Address at the Rameswaram Temple on Real Worship
Context: It is in love that religion exists and not in ceremony, in the pure and sincere love in the heart. Unless a man is pure in body and mind, his coming into a temple and worshipping Shiva is useless. The prayers of those that are pure in mind and body will be answered by Shiva, and those that are impure and yet try to teach religion to others will fail in the end. External worship is only a symbol of internal worship; but internal worship and purity are the real things. Without them, external worship would be of no avail. Therefore you must all try to remember this.
People have become so degraded in this Kali Yuga that they think they can do anything, and then they can go to a holy place, and their sins will be forgiven. If a man goes with an impure mind into a temple, he adds to the sins that he had already, and goes home a worse man than when he left it.

Context: There are several sorts of religions, not only in different parts of the island, but even in every town; some worshipping the sun, others the moon or one of the planets. Some worship such men as have been eminent in former times for virtue or glory, not only as ordinary deities, but as the supreme god. Yet the greater and wiser sort of them worship none of these, but adore one eternal, invisible, infinite, and incomprehensible Deity; as a Being that is far above all our apprehensions, that is spread over the whole universe, not by His bulk, but by His power and virtue; Him they call the Father of All, and acknowledge that the beginnings, the increase, the progress, the vicissitudes, and the end of all things come only from Him; nor do they offer divine honours to any but to Him alone. And, indeed, though they differ concerning other things, yet all agree in this: that they think there is one Supreme Being that made and governs the world, whom they call, in the language of their country, Mithras. They differ in this: that one thinks the god whom he worships is this Supreme Being, and another thinks that his idol is that god; but they all agree in one principle, that whoever is this Supreme Being, He is also that great essence to whose glory and majesty all honours are ascribed by the consent of all nations.
