Shloka 183

उत्पन्नत्यागिन: सर्वे जना आसन्नमत्सरा: । प्राचीन कालके ब्राह्मण सत्यभाषण और इन्द्रिय-संयमरूप यज्ञका अनुष्ठान करते थे। वे परम पुरुषार्थ (मोक्ष)के प्रति लोभ रखते थे, उन्हें लौकिक धनकी प्यास नहीं रहती थी, वे उस ओरसे सदा तृप्त रहते थे। वे सब लोग प्राप्त वस्तुका त्याग करनेवाले और ईर्ष्या-द्वेषसे रहित थे

utpanna-tyāginaḥ sarve janā āsann amatsarāḥ | prācīna-kālake brāhmaṇāḥ satya-bhāṣaṇaṃ ca indriya-saṃyama-rūpa-yajñasya anuṣṭhānaṃ kurvanti sma | te parama-puruṣārthaṃ (mokṣaṃ) prati lobhaṃ dadhati sma; teṣāṃ laukika-dhana-tṛṣṇā na āsīt; tatra te sadā tṛptā āsan | te sarve prāpta-vastu-tyāginaḥ īrṣyā-dveṣa-rahitāś ca āsan |

Chulādhāra said: In ancient times, people were free from envy and lived without malice. The brāhmaṇas of that age performed a sacrifice made of truthfulness in speech and restraint of the senses. Their longing was directed toward the highest human goal—liberation—and they felt no thirst for worldly wealth, remaining ever content in that regard. All of them were ready to relinquish what they had obtained and were devoid of jealousy and hatred.

Educational Q&A

True sacrifice is ethical and inward: truthfulness and sense-restraint. One should aspire for moksha, remain content without craving for wealth, and abandon envy, hatred, and attachment even to legitimately obtained possessions.

Chulādhāra describes an idealized ancient age, praising the conduct of earlier brāhmaṇas and people: they practiced inner yajña through truthful speech and self-control, sought liberation rather than riches, and lived without jealousy or malice.
