Ribhu: Listen! All is only Brahman. I say, in the name of Shiva, this is the truth, this is the truth. O Master of yoga! There is nothing else whatsoever.
2. The unreal is not even an atom; all this, surely, is not even an atom. The body, too, is not even an atom. There is nothing else whatsoever.
3. All is only the Self, the pure Self. All is only Consciousness without a second. The Self is eternal, spotless and pure. There is nothing else whatsoever.
4. If the Self is considered as merely atomic in dimension, all is not even an atom. Absence of sankalpa, too, is a mere atom. There is nothing else whatsoever.
5. Sankalpa is only Consciousness. Consciousness is the highest state. Bliss is the supreme measure. All this that is seen is nothing.
6. The syllable Om is only Consciousness. Consciousness itself is all. Bliss is the supreme measure. All this that is seen is nothing.
