Lākṣāgṛha Planning
तदभ्यासकृतं मत्वा रात्रावपि स पाण्डव: । योग्यां चक्रे महाबाहुर्धनुषा पाण्डुनन्दन:,उसे अभ्यासका ही चमत्कार मानकर महाबाहु पाण्डुनन्दन अर्जुन रातमें भी धनुर्विद्याका अभ्यास करने लगे
tadabhyāsakṛtaṃ matvā rātrāv api sa pāṇḍavaḥ | yogyāṃ cakre mahābāhur dhanuṣā pāṇḍunandanaḥ ||
Thinking that this was achieved only through constant practice, that mighty-armed son of Pāṇḍu—the Pāṇḍava (Arjuna)—began to train with the bow even at night, resolving to make himself fully proficient. The verse highlights disciplined effort and self-cultivation as the ethical basis of excellence, rather than reliance on chance or mere talent.
वैशम्पायन उवाच
Excellence is grounded in abhyāsa—steady, repeated practice. The verse ethically frames skill as something earned through disciplined effort and vigilance, not merely inherited status or sudden inspiration.
After witnessing a display of skill and concluding it must be the result of rigorous training, Arjuna (the Pāṇḍava) intensifies his own preparation, practicing archery even at night to become fully proficient.
