Śrīmad-Bhāgavatam · Text 3.1.40
Who is speaking and story frame
अहो पृथापि ध्रियतेऽर्भकार्थे
राजर्षिवर्येण विनापि तेन ।
यस्त्वेकवीरोऽधिरथो विजिग्ये
धनुर्द्वितीय: ककुभश्चतस्र: ॥ ४० ॥
aho pṛthāpi dhriyate ’rbhakārthe
rājarṣi-varyeṇa vināpi tena
yas tv eka-vīro ’dhiratho vijigye
dhanur dvitīyaḥ kakubhaś catasraḥ
O my lord, is Pṛthā still living? She lived only for the sake of her fatherless children; otherwise it was impossible for her to live without King Pāṇḍu, who was the greatest commander and who alone conquered the four directions simply with the help of a second bow.
