One should not make loud abuse or censure. Onc should not speak useless words. One should forbear from knavery and from accusing others. One should observe the vow of truthfulness, be sparing of speech, and always careful. By acting thus one will have his organ of speech well-governed.
नाक्रोशमृच्छेन्न वृथा वदेच्च न पैशुनं जनवादं च कुर्यात्। स्तथास्य वाग्द्वारमथो सुगुप्तम्॥
