Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
भीष्म उवाच दुराचारा दुर्विचिष्टा दुष्प्रज्ञा: प्रियसाहसा: । असंतस्त्विति विख्याता: संतश्षाचारलक्षणा:,भीष्मजीने कहा--राजन्! जो दुराचारी, बुरी चेष्टावाले, दुर्बुद्धि और दुः:साहसको प्रिय माननेवाले हैं, वे दुष्टात्माके नामसे विख्यात होते हैं। श्रेष्ठ पुरुष तो वही हैं, जिनमें सदाचार देखा जाय--सदाचार ही उनका लक्षण है
bhīṣma uvāca durācārā durviciṣṭā duṣprajñāḥ priyasāhasāḥ | asantastv iti vikhyātāḥ santaś cācāralakṣaṇāḥ ||
भीष्म उवाच—दुराचाराः दुर्विचेष्टाः दुष्प्रज्ञाः प्रियसाहसाः । असन्तस्त्विति विख्याताः सन्तश्चाचारलक्षणाः ॥
भीष्म उवाच
Moral identity is determined by conduct: the wicked are characterized by corrupt behavior, distorted actions, poor judgment, and love of reckless daring, while the good are defined by consistent right conduct (ācāra) as their distinguishing mark.
In the Shanti Parva’s instruction on dharma, Bhishma is teaching Yudhishthira how to discern virtue from vice, offering a practical criterion: observe a person’s conduct, because it reveals whether one is sat (good) or asat (wicked).
