Adhyāya 180: Jīva, Śarīra, and the Fire Analogy (भृगु–भरद्वाज संवादः)
स्वभावादेव संदृश्या वर्तमाना: प्रवृत्तय: । स्वभावनिरता: सर्वाः परितुष्येन्न केनचित्,“ऐसा समझना चाहिये, पूर्वकृत कर्मानुसार बने हुए स्वभावसे ही प्राणियोंकी वर्तमान प्रवृत्तियाँ प्रकट हुई हैं; अत: समस्त प्रजा स्वभावमें ही तत्पर है, उनका दूसरा कोई आश्रय नहीं है। इस रहस्यको समझकर मनुष्यको किसी भी परिस्थितिमें संतुष्ट नहीं होना चाहिये
svabhāvādeva saṃdṛśyā vartamānāḥ pravṛttayaḥ | svabhāvaniratāḥ sarvāḥ parituṣyenna kenacit ||
“Know that the tendencies seen in beings manifest in the present from their very nature—shaped by prior deeds. All creatures are absorbed in their own nature and have no other refuge. Understanding this subtle truth, a person should not become complacently ‘satisfied’ in any condition.”
भीष्म उवाच
Present behavior arises from svabhāva, which is conditioned by past karma; therefore one should not excuse oneself or become complacent, but consciously strive to refine conduct in line with dharma.
In the Shanti Parva’s instruction to Yudhishthira, Bhishma explains how innate disposition governs people’s actions and urges a disciplined, non-complacent pursuit of ethical improvement.
