अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत् | स्वाध्यायाभ्यसनं चैव वाङ्मयं तप उच्यते
anudvegakaraṃ vākyaṃ satyaṃ priyahitaṃ ca yat . svādhyāyābhyasanaṃ caiva vāṅmayaṃ tapa ucyate
那不引起不安、真实、悦耳且有益的言语，以及研习经典的行为，被称为言语的苦行（Tapas）。
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.
实践言语苦行之人，其言语不会给他人带来痛苦，反而会给他人带来愉悦和慰藉，并对所有人有益。言语器官会极大地分散心智。控制言语是一项困难的修行，但如果你想获得至高无上的平静，就必须实践它。对于一个有坚定决心、真诚目的、钢铁意志、耐心和毅力的人来说，没有什么是不可能的。摩奴法典（Manu Smriti）中说：“ सत्यं ब्रूयात् प्रियं ब्रूयात् न ब्रूयात् सत्यमप्रियम्। प्रियं च नानृतं ब्रूयात् एष धर्मः सनातनः।। ”（应说真话，应说悦耳之语。不应说真实但不悦耳之语，也不应说悦耳但不真实之语。这是永恒的达摩（Dharma）。）言语若要成为苦行，必须同时具备本节经文中所述的四种特质：不引起不安、真实、悦耳和有益。如果缺少其中任何一种特质，它就不能构成言语的苦行。言语可能悦耳，但如果缺乏其他三种特质，它就不再是言语的苦行。
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.
