Shloka 25
Adhyāya 33 — Yudhiṣṭhira’s Post-Conflict Remorse and Inquiry on Āśrama Discipline (शोक-विमर्शः, आश्रम-जिज्ञासा)
इदं तु श्रूयते पार्थ युद्धे देवासुरे पुरा । असुरा क्रातरो ज्येष्ठा देवाश्नापि यवीयस:
idaṃ tu śrūyate pārtha yuddhe devāsure purā | asurā krātarā jyeṣṭhā devāś cāpi yavīyasaḥ ||
婆尔他（Pārtha）啊，古传亦云：在久远之初，天神（Deva）与阿修罗（Asura）交战之时，阿修罗为长者，根基更早更固；天神则较为年少。此言引出道德省思：资历与先前之强盛，并不足以自保正当之胜；胜负所系，在于法（dharma）、戒律与那更深的秩序——它扶持诸天。
व्यास उवाच
Educational Q&A
The verse introduces a traditional example to suggest that mere seniority or raw strength (the Asuras being older/stronger) is not the decisive measure of rightful success; the deeper implication is that dharma and the sustaining cosmic order ultimately determine outcomes.
Vyāsa addresses Arjuna (Pārtha) and cites an ancient report about a primordial Deva–Asura conflict, noting that the Asuras were the elder/stronger party while the Devas were younger—setting up a comparison for the ethical argument being developed in the surrounding discourse.
