Shloka 56
Nakula’s Adaptive Counsel to Kṛṣṇa in the Kuru Assembly (उद्योगपर्व, अध्याय ७८)
दैवं तु न मया शक्यं कर्म कर्तु कथंचन । मैं पुरुषार्थसे जितना हो सकता है
daivaṃ tu na mayā śakyaṃ karma kartuṃ kathaṃcana |
アルジュナは言った。「だが宿命により定められたことを、我は如何なる仕方でも成し遂げることはできぬ。我は人の力の及ぶ限りを尽くして、和議と和解のために最大の努力をなそう。されど運命の勅令—prārabdha（既熟業）—を避け、あるいは改めることは、我が力の外にある。」

Educational Q&A
The verse frames an ethical balance: one must apply maximum human effort toward a righteous goal (here, peace), while recognizing that the final outcome may be governed by daiva/prārabdha beyond personal control. Responsibility lies in sincere effort, not in guaranteeing results.
In the Udyoga Parva’s pre-war negotiations, Arjuna expresses resolve to strive for a settlement, yet acknowledges that if destiny has fixed the course toward conflict, he cannot overturn that decree—only act rightly within his capacity.
