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
قال أرجونا: «إني فاعلٌ ذلك حقًّا—ولكن إلى أقصى ما يبلغه سعيُ البشر.»
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.
