Sanskrit:
श्रुत्वैतद् भगवान् रामो विपक्षीयनृपोद्यमम् । कृष्णं चैकं गतं हर्तुं कन्यां कलहशङ्कित: ॥ २० ॥ बलेन महता सार्धं भ्रातृस्नेहपरिप्लुत: । त्वरित: कुण्डिनं प्रागाद् गजाश्वरथपत्तिभि: ॥ २१ ॥
ITRANS:
śrutvaitad bhagavān rāmovipakṣīya nṛpodyamamkṛṣṇaṁ caikaṁ gataṁ hartuṁkanyāṁ kalaha-śaṅkitaḥ
Translation:
When Lord Balarāma heard about these preparations of the inimical kings and how Lord Kṛṣṇa had set off alone to steal the bride, He feared that a fight would ensue. Immersed in affection for His brother, He hurried to Kuṇḍina with a mighty army consisting of infantry and of soldiers riding on elephants, horses and chariots.
