In plain words
They can perceive. The Ātma is separate from all the senses. I have no connection with these senses. Sight belongs purely to the Ātma. The eye of flesh only takes shape as one sense. The divine principle that lies between this eye and colour is this Ātma principle. The divinity that lies between the ear and sound is the Ātma principle. Even with eyes, one may be unable to see colour. If the sense were truly Satya, why should the eye not see colour? No. Between the eye and colour there is a divine, formless light. The eye has the power of seeing alone. The ear has the power of hearing alone. The eye has the power of seeing alone. The tongue can only taste. Each of these senses can do only one thing each. But the senses cannot make everything happen. The eye can see, but can it hear? The ear can hear, but can it see? No. So to each sense is given only one kind of power. The divinity that holds all powers is the Ātma alone.
In many vessels we may see many kinds of reflection. This is called ghaṭākāśa, paṭākāśa and maṭhākāśa. In a pot, the sky is seen in the water. How long is the sky seen in the pot? Only so long as the pot is there as its vessel is the sky seen in this pot. When the pot is broken, the sky is not seen. Then where has the sky gone? It stays in its own true form. The sky did not come into this pot. Nor did it go when the pot broke. It went on being seen as long as there was water in the pot. As soon as the pot broke, the water ran out. The sky was not seen inside it. In the very same way, the body is a pot. Within this pot called the body is the water called the mind. In it the sky called the Ātma principle should be reflected. But only so long as this pot is there is it seen in it. Even after the pot is broken, it is there. But it is not seen. Just because it is not seen, one must not argue that it is not there. So, ‘Ātmavat sarvabhūtāni’: in all things, everywhere, at all times, that alone is Satya. They spoke of paṭākāśa. On a canvas they show a sky in paint. But when we tear up that picture, the sky does not go. You tore up the paper. But you did not tear the sky. In the very same way, Vedānta has set out three principles of space: ghaṭākāśa, paṭākāśa and maṭhākāśa.
The Ātma is undivided. It is this they named Satyaṃ Śivaṃ Sundaraṃ.
