“X” and “Y” are simply the algebraic unknown quantities. We have seen that all knowledge is a combination, and this world, the universe, is a combination, and intelligence is similarly a combination. If it is internal intelligence it is “Y” plus the mind, if an external object, it is “X” plus the mind. Knowledge is a combination of “Y” plus the mind and matter is a combination of “X” plus the mind. We first take the internal group. Intelligence which we see in Nature cannot be wholly in Nature, because intelligence itself is a compound of “Y” plus the mind. “Y” comes from the Self. So the intelligence that we know is a compound of the power of the light of the soul plus nature. Similarly, the existence which we know must be a compound of “X” plus the mind. We find therefore that in these three factors, I exist, I know and I am blessed, the idea that I have no want, which comes from time to time, is the central idea, the grand basic idea of our life, and when it becomes limited, and becomes a compound, we think it happiness and misery. These factors manifest as existence phenomenal, knowledge phenomenal, and love phenomenal. Every man exists, and every man must know, and every man is made for bliss. He cannot help it. So through all existence; animals and plants, from the lowest to the highest existence, all must love. You may not call it love; but they must all exist, must all know and must all love. So this existence which we know is a compound of “X” and the mind, and knowledge also is a compound of that “Y” inside plus mind, and that love also is a compound of that “Y” and mind. Therefore these three factors which come from inside and are combining themselves with the external things to manufacture phenomenal existence, knowledge and love, are called by the Vedantists “Existence Absolute, Knowledge Absolute, Bliss Absolute.”
