Aṃśāvataraṇa-kathana (Catalog of Divine/Asuric Portions in Human Births) — Chapter 61
बीभत्सुर्वासुदेवेन सहितो नृपसत्तम । नातिभारो हि पार्थस्य केशवेन सहाभवत्
bībhatsur vāsudevena sahito nṛpasattama | nātibhāro hi pārthasya keśavena sahābhavat ||
हे नृपश्रेष्ठ! वासुदेव (श्रीकृष्ण) सोबत असता बीभत्सु अर्जुनाला ते कार्य अतिभार वाटले नाही; कारण केशव संगतीने पार्थावरचा भार अधिक होत नाही.
वैशम्पायन उवाच
A difficult duty becomes bearable and rightly executed when one is supported by wise, dharmic guidance—here symbolized by Arjuna’s strength being steadied by Kṛṣṇa’s presence.
The narrator notes that Arjuna, traveling/acting together with Kṛṣṇa, did not experience the undertaking as an excessive burden; Kṛṣṇa’s companionship makes the task manageable.
