There is then but one all-comprehending existence, and that one appears as manifold. This Self or Soul or Substance is all that exists in the universe. That Self or Substance or Soul is, in the language of non-dualism, the Brahman appearing to be manifold by the interposition of name and form. Look at the waves in the sea. Not one wave is really different from the sea, but what makes the wave apparently different? Name and form; the form of the wave and the name which we give to it, "wave". This is what makes it different from the sea. When name and form go, it is the same sea. Who can make any real difference between the wave and the sea? So this whole universe is that one Unit Existence; name and form have created all these various differences. As when the sun shines upon millions of globules of water, upon each particle is seen a most perfect representation of the sun, so the one Soul, the one Self, the one Existence of the universe, being reflected on all these numerous globules of varying names and forms, appears to be various. But it is in reality only one. There is no "I" nor "you"; it is all one. It is either all "I" or all "you". This idea of duality, calf two, is entirely false, and the whole universe, as we ordinarily know it, is the result of this false knowledge.
