First Pâda: Sabda proves difference

As to sound (speech; sabda) it is specially apparent that it possesses the power of denoting only such things as are affected with difference. Speech operates with words and sentences. Now a word (pada) originates from the combination of a radical element and a suffix, and as these two elements have different meanings it necessarily follows that the word itself can convey only a sense affected with difference. And further, the plurality of words is based on plurality of meanings; the sentence therefore which is an aggregate of words expresses some special combination of things (meanings of words), and hence has no power to p. 41 denote a thing devoid of all difference.--The conclusion is that sound cannot be a means of knowledge for a thing devoid of all difference.
