अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत् | स्वाध्यायाभ्यसनं चैव वाङ्मयं तप उच्यते
anudvegakaraṃ vākyaṃ satyaṃ priyahitaṃ ca yat . svādhyāyābhyasanaṃ caiva vāṅmayaṃ tapa ucyate
那種不引起不安、真實、悅耳且有益的言語；以及研習經典的實踐，被稱為言語的苦行。
That speech which causes no pain, which is true, agreeable and beneficial; as well as the practice of study of the scriptures,-is said to be austerity of speech.
實踐言語苦行之人的話語不會傷害他人，反而會給他人帶來歡樂和慰藉，並對所有人有益。言語器官會導致心靈極大的散亂。控制言語是一項艱難的修持，但若想獲得至高無上的平靜，就必須實踐。對於意志堅定、目標真誠、鋼鐵般意志、耐心和毅力之人，沒有什麼是不可能的。正如《摩奴法典》（Manu Smriti）所言：「應說真話，應說悅耳之話。不應說真實但不悅耳之話，也不應說悅耳但不真實之話。此乃永恆的「達摩」（Dharma）。」言語若要成為苦行，必須同時具備本節所述的四種特質：不引起不安或不痛苦、真實、悅耳和有益。若缺少其中任何一項，便不能構成言語的苦行。
The words of the man who practises the austerity of speech cannot cause pain to others. His words will bring cheer and solace to others. His words prove beneficial to all. The organ of speech causes great distraction of mind. Control of speech is a difficult discipline but you will have to practise it if you want to attain supreme peace. Nothing is impossible for a man who has a firm determination? sincerity of purpose? iron will? patience and perseverance.It is said in Manu Smritiसत्यं ब्रूयात् प्रियं ब्रूयात् न ब्रूयात् सत्यमप्रियम्।प्रियं च नानृतं ब्रूयात् एष धर्मः सनातनः।।One should speak what is true one should speak what is pleasant. One should not speak what is true if it is not pleasant nor what is pleasant if it is false. This is the ancient Dharma.Excitement Pain to living beings.Speech? to be an austerity? must form an invariable combination of all the four attributes mentioned in this verse? viz.? nonexciting or nonpainful? truthful? pleasant and beneficial if it is wanting in one or the other of these attributes? it cannot form the austerity of speech. Speech may be pleasant but it it is lacking in the other three attributes? it will no longer be an austerity of speech.
