ब्राह्मणस्य पूर्वतरा वृत्तिः — The Earlier Ideal Conduct of a Brahmana
River-of-Saṃsāra Metaphor
सर्वे समरमासाद्य न श्रूयन्ते पराजिता: । सर्वे सत्यव्रतपरा: सर्वे कामविहारिण:
sarve samaram āsādya na śrūyante parājitāḥ | sarve satyavrataparāḥ sarve kāmavihāriṇaḥ ||
அவர்கள் அனைவரும் போர்க்களத்தில் நுழைந்தபின் தோல்வியுற்றதாகக் கேள்விப்படப்படவில்லை. அனைவரும் சத்தியவிரதத்தில் உறுதியானவர்கள்; அனைவரும் தம் விருப்பத்திற்கேற்ப, சுயாதீனமாக வாழ்ந்து உலாவுபவர்கள்.
भीष्म उवाच
The verse praises an ideal type of person: undefeated in conflict, grounded in truth (satyavrata), and capable of enjoying life without losing self-mastery—suggesting that ethical integrity and inner discipline support strength and success.
Bhishma is describing a group (implied from the surrounding discourse) whose reputation is exemplary: tradition does not record them as ever being defeated in battle, and their character is marked by truthfulness and a free, confident mode of living.
