Adhyāya 180: Jīva, Śarīra, and the Fire Analogy (भृगु–भरद्वाज संवादः)
स्वभावादेव संदृश्या वर्तमाना: प्रवृत्तय: । स्वभावनिरता: सर्वाः परितुष्येन्न केनचित्
svabhāvādeva saṃdṛśyā vartamānāḥ pravṛttayaḥ | svabhāvaniratāḥ sarvāḥ parituṣyenna kenacit ||
“应当明白:众生现前所见的种种趋向,皆由其自性而显现;而此自性又为往昔业行所塑成。万类沉浸于各自之性,别无依止。洞悉此微妙之理,人不应在任何境遇中自满而安逸。”
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.
