भीष्म उवाच दुराचाराश्र दुर्धर्षा दुर्मुखा श्वाप्पसाधव: । साधव: शीलसम्पन्ना: शिष्टाचारस्य लक्षणम्
bhīṣma uvāca: durācārāś ca durdharṣā durmukhā śvāpadāḥ asādhavaḥ | sādhavaḥ śīla-sampannāḥ śiṣṭācārasya lakṣaṇam ||
Bhishma said: “The wicked—like wild beasts—are of corrupt conduct, hard to restrain, and harsh-mouthed in speech. The good, however, are endowed with character. Now I shall state the defining marks of proper conduct (śiṣṭācāra).”
भीष्म उवाच
Bhishma contrasts the traits of the wicked (corrupt conduct, ungovernable nature, harsh speech—likened to wild beasts) with the traits of the virtuous (good character), and introduces a forthcoming definition of śiṣṭācāra—normative, dharma-aligned conduct.
In the Anuśāsana Parva’s instruction section, Bhishma continues advising Yudhiṣṭhira on ethical life and social dharma, setting up a discussion on the marks of proper conduct by first distinguishing bad and good persons.
