Śrīmad-Bhāgavatam · Text 10.48.24
Who is speaking and story frame
स त्वं प्रभोऽद्य वसुदेवगृहेऽवतीर्ण:
स्वांशेन भारमपनेतुमिहासि भूमे: ।
अक्षौहिणीशतवधेन सुरेतरांश-
राज्ञाममुष्य च कुलस्य यशो वितन्वन् ॥ २४ ॥
sa tvam prabho ’dya vasudeva-gṛhe ’vatīrṇaḥ
svāṁśena bhāram apanetum ihāsi bhūmeḥ
akṣauhiṇī-śata-vadhena suretarāṁśa-
rājñām amuṣya ca kulasya yaśo vitanvan
You are that very same Supreme Person, my Lord, and You have now appeared in the home of Vasudeva with Your plenary portion. You have done this to relieve the earth’s burden by killing hundreds of armies led by kings who are expansions of the demigods’ enemies, and also to spread the fame of our dynasty.
