Shloka 13
Bhūta-guṇa-saṃkhyāna
Enumeration of the Properties of the Elements and Cognitive Faculties
एवं स्वभावमेवेदमिति विद्वान् न मुहृति । अशोचचन्नप्रहृष्यन् हि नित्यं विगतमत्सर:
evaṁ svabhāvam evedam iti vidvān na muhṛti | aśocan na prahṛṣyan hi nityaṁ vigata-matsaraḥ ||
了知“此世实如是——恒常变易”，智者片刻亦不迷惑。他不悲不喜；常离嫉妒与恶意，于世间诸变之中，内心安住而不动。

Educational Q&A
The verse teaches equanimity grounded in insight: since change is the world’s inherent nature (svabhāva), the wise do not fall into delusion, nor swing between grief and elation; they cultivate freedom from envy and hostility as a stable ethical disposition.
Vyāsa is instructing on the marks of a truly wise person in the Śānti Parva’s discourse on peace and right conduct: he describes the inner stance of the knower—unconfused by worldly change, emotionally balanced, and purified of envy.
