बभूव कल्प: कौन्तेय: प्रहृष्ट: साहकर्मणि । वज्नाभं ततश्नक्रं ददौ कृष्णाय पावक:,वह रथ, धनुष तथा अक्षय तरकस पाकर कुन्तीनन्दन अर्जुन अत्यन्त प्रसन्न हो अग्निकी सहायता करनेमें समर्थ हो गये। तदनन्तर पावकने भगवान् श्रीकृष्णको एक चक्र दिया, जिसका मध्यभाग वज्धके समान था
babhūva kalpaḥ kaunteyaḥ prahṛṣṭaḥ sāhakarmaṇi | vajrābhaṃ tataś cakraṃ dadau kṛṣṇāya pāvakaḥ ||
Vaiśampāyana said: Kuntī’s son Arjuna became fully capable and delighted in rendering assistance. Thereupon Pāvaka (Agni), as a token of divine support for their undertaking, bestowed upon Kṛṣṇa a discus whose hub was like a thunderbolt—an emblem of irresistible power placed in the service of their righteous purpose.
वैशम्पायन उवाच
When a task is undertaken with steadfast cooperation and a sense of rightful purpose, supportive power (symbolized by Agni’s gift) aligns with the agents of action; capability and joy in service become signs of readiness for dharmic responsibility.
Arjuna becomes eager and fully able to assist in the undertaking, and Agni (Pāvaka) rewards and equips the allies by giving Kṛṣṇa a formidable discus described as thunderbolt-like at its center.
