In plain words
Refuge in this oneness. ‘Come to Me alone for refuge’, ‘I shall set you free; do not grieve’: He said ‘I’. In every word too He kept using the word I, I, I. So great is the power of this word I. From the millionaire to the man too poor for a meal, from the scholar to the unlettered, from the ignorant to the wise, when they speak of themselves, when they tell of themselves, they cannot use a second word without the word ‘I’ coming in. ‘I came’, ‘I am going’, ‘I saw’, ‘I heard’, ‘I am speaking’: in all these, every one, the ‘I’ stays one and the same. What is this ‘I’? That is just it: in Vedānta there are two words, only two. This, and I: only these two are important. This, what is it? A handkerchief. What is this? A glass. What is this? A table. Who is he? A man. What is this? A building. Without this, this, this, we cannot discuss any single object at all, nor see it, nor inquire into it. This whole world, all of it, built up of what is seen, is just ‘this’; even a little boy who cannot yet talk, as he walks along holding his mother's hand, says, ‘Mother! What is “this”? What is this? What is this?’ and keeps using this, this. Mother! Why “this”? All of it is this, ‘this’: that is to say, ‘this’ is the name for the world built up of what is seen. ‘This’ is the seen; I myself, who see this seen, am the seer. The one who is ‘I’ is the seer.
The whole world is only the seen: look at anything you like? Hear anything you like? Read anything you like? Hold anything you like? Do anything you like. If all of it is only this, then here two kinds of science are teaching. What is the physical science? Why is there a spiritual science? But the science of Vedānta is the very union of the two. The question ‘why’ comes up in Vedānta too. The question ‘what’ comes up in physics too. Physical science and the science of Vedānta, the two joined together, are precisely the answers to this ‘what’ and ‘why’. But today's physical science. He only tells what, what: that this earth is turning.
