Udyoga Parva, Adhyāya 73 — Kr̥ṣṇa’s Appraisal of Bhīma’s Altered Temper and Reaffirmation of Martial Resolve
स मन्युवशमापतन्न: स्वभावं दुष्टमास्थित: । स्वभावात् पापमभ्येति तृणैश्छन्न इवोरग:
sa manyuvaśam āpatannaḥ svabhāvaṃ duṣṭam āsthitaḥ | svabhāvāt pāpam abhyeti tṛṇaiś channa ivoragaḥ ||
तो क्रोधाच्या आधीन होऊन दुष्ट स्वभावाचा आश्रय घेतो. स्वभावतःच तो पापाकडे झुकतो—काडीकचऱ्यात लपलेल्या सर्पाप्रमाणे, लपूनही दुसऱ्याला दंश करण्यास तत्पर.
भीम उवाच
Unchecked anger (manyu) can dominate a person and harden into a wicked disposition; when one normalizes such a nature, wrongdoing becomes habitual and dangerous—like a concealed snake that harms without warning.
Bhima condemns an opponent’s moral character, portraying him as ruled by anger and innately inclined to harmful, sinful action, using the image of a snake hidden in grass to stress concealed danger.
