Shloka 37
Karṇa’s advance against the Pāṇḍava host; Arjuna’s clash with the Saṃśaptakas (कर्णस्य पाण्डवसेनाप्रवेशः—अर्जुनस्य संशप्तकसंप्रहारः)
नाशकत् तान्यभेद्यानि यदा भेत्तुं पुरंदर:
nāśakat tāny abhedyāni yadā bhettuṃ purandaraḥ | tapa ugraṃ samāsthāya niyame parame sthitāḥ ||
ドゥルヨーダナは言った。「破城者（インドラ）が、ブラフマーの恩寵を得たあの不落の城塞を破れなかったとき、彼は恐れを抱き、そこから退いて城々を捨てた。そして神々とともにブラフマーのもとへ赴き、あのダーナヴァたちの圧政を訴えた。」

Educational Q&A
The passage highlights that power fortified by tapas (austerity) and strict niyama (discipline) can make even the seemingly invincible hesitate; boons and titles do not guarantee success, and prudent recourse to higher counsel (Brahmā) becomes necessary when force fails.
Duryodhana cites an earlier divine-demonic episode: after the Dānavas were defeated, Tārakāsura’s sons performed severe austerities and became protected by impregnable cities; Indra could not pierce them, grew fearful, withdrew, and went with the gods to Brahmā to report their oppression and seek a remedy.
