मर्माण्यस्थीनि हृदयं तथासून् रूक्षा वाचो निर्दहन्तीह पुंसाम् । तस्माद् वाचमुषती रूक्षरूपां धर्मारामो नित्यशो वर्जयीत
marmāṇy asthīni hṛdayaṃ tathā sūn rūkṣā vāco nirdahantīha puṃsām | tasmād vācam uṣatīṃ rūkṣarūpāṃ dharmārāmo nityaśo varjayīta ||
世间粗暴刻薄之言，灼伤人的要害、骨骼、心脏，乃至生命之息。故乐于法者，当恒常远离那灼热而粗砺的言语。

Educational Q&A
Speech can injure as deeply as physical violence: harsh, abrasive words are said to burn a person’s most sensitive inner and vital supports. Hence, a dharma-minded person should practice restraint and avoid speech that wounds or inflames.
In Udyoga Parva, within a didactic exchange, the speaker Haṃsa offers moral instruction. This verse specifically warns about the destructive power of harsh speech and recommends disciplined, dharma-aligned communication.
