must still be infinity, for it cannot be separated from itself. Suppose there is an infinite ocean of water, could you take up one drop from there? If you could, that ocean would no longer be infinite, that drop would limit it. The infinite cannot be divided by any means. But there are stronger proofs that the Self is One. Not only so, but that the whole universe is one. We will once more take up our “X” and “Y”. We have shown how what we call the external world is “X” plus mind, and the internal world “Y” plus mind. “X” and “Y” are both unknown quantities, unknown and unknowable. What is the mind? The mind is the “time, space and causation.” This idea is the nature of the mind. You can never think without time, you can never conceive of anything without space, and you can never imagine anything without causation. These three are the forms in which both “X” and “Y” are caught, and which become the mind. Beyond that there is nothing to the mind. Take off these three forms which of themselves do not exist,--what remains? It is all one; “X” and “Y” are one. It is only this mind, this form, that has limited them apparently, and made them differ as internal and external world. “X” and “Y” are both unknown and unknowable. We cannot attribute any quality to them. As such they are both the same. That which is qualitiless and attributeless and absolute must be one. There cannot be two absolutes. When there are no qualities there can be only One. “X” and “Y” are both without qualities because they take qualities only in the mind, therefore this “X” and “Y” are one.
