पौरुषं कर्म दैवं च फलवृत्ति: स्वभावत: । त्रय एते5पृथग्भूता न विवेक॑ तु केचन,कुछ विद्वान् कहते हैं कि पुरुषार्थ, दैव और स्वभावसे अनुगृहीत कर्म--इन तीनोंके सहयोगसे फलकी सिद्धि होती है। ये तीनों मिलकर ही कार्यसाधक होते हैं। इनका अलग-अलग होना कार्यकी सिद्धिका हेतु नहीं होता है
pauruṣaṁ karma daivaṁ ca phalavṛttiḥ svabhāvataḥ | traya ete ’pṛthagbhūtā na vivekaṁ tu kecana ||
Some declare that the fruition of action arises naturally from the combined working of three factors: human effort, destiny, and innate disposition. These three bring about results only as an inseparable whole; taken separately, none is sufficient for success.
व्यास उवाच
Results arise from the joint operation of human effort (pauruṣa), destiny (daiva), and innate nature (svabhāva). Treating any one factor as the sole cause is an incomplete view; effective action and its fruition depend on their combined interplay.
In the didactic setting of the Śānti Parva, Vyāsa delivers a philosophical clarification about causality and moral agency, explaining how success or failure in action is produced through multiple intertwined causes rather than a single isolated determinant.
