Shrimad Bhagavad Gita
अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत् । स्वाध्यायाभ्यसनं चैव वाङ्मयं तप उच्यते ॥ १७-१५॥
Speech that hurts no one, that is true, is pleasant to listen to and beneficial, and also the practice of regular recitation of the Vedas - all this is said to be an austerity of speech.
english translation
जो वाक्य (भाषण) उद्वेग उत्पन्न करने वाला नहीं है, जो प्रिय, हितकारक और सत्य है तथा वेदों का स्वाध्याय अभ्यास वाङ्मय (वाणी का) तप कहलाता है।
