And as by no possible means of analysis can we separate the word from the idea this Om and the eternal Sphota are inseparable; and therefore, it is out of this holiest of all holy words, the mother of all names and forms, the eternal Om, that the whole universe may be supposed to have been created. But it may be said that, although thought and word are inseparable, yet as there may be various word-symbols for the same thought, it is not necessary that this particular word Om should be the word representative of the thought, out of which the universe has become manifested. To this objection we reply that this Om is the only possible symbol which covers the whole ground, and there is none other like it. The Sphota is the material of all words, yet it is not any definite word in its fully formed state. That is to say, if all the peculiarities which distinguish one word from another be removed, then what remains will be the Sphota; therefore this Sphota is called the Nâda-Brahma, the Sound-Brahman.
