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
アルジュナは言った。「それは必ず成そう—ただし、人の努力が成し得る極みにおいて。」
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.
