Nakula’s Adaptive Counsel to Kṛṣṇa in the Kuru Assembly (उद्योगपर्व, अध्याय ७८)
अहं हि तत् करिष्यामि परं पुरुषकारत:
ahaṃ hi tat kariṣyāmi paraṃ puruṣakārataḥ
阿周那说道:“我必将为之——但也只尽人力所能及之极致。”
अर्जुन उवाच
One should commit to righteous action with full personal exertion (puruṣakāra), while recognizing that one’s capacity has limits; ethical responsibility lies in sincere effort rather than guaranteed outcomes.
Arjuna responds to a request or proposed course of action, declaring his readiness to carry it out, but qualifying his promise as being within the bounds of what human effort can achieve.
