Srimad-Bhagavatam: Canto 5 - Chapter 1 - Verse 1
श्रीशुक उवाचभरतस्तु महाभागवतो यदा भगवतावनितलपरिपालनाय सञ्चिन्तितस्तदनुशासनपर: पञ्चजनीं विश्वरूपदुहितरमुपयेमे ॥ १ ॥
śrī-śuka uvācabharatas tu mahā-bhāgavato yadā bhagavatāvani-tala-paripālanāya sañcintitas tad-anuśāsana-paraḥ pañcajanīṁ viśvarūpa-duhitaram upayeme.
Śukadeva Gosvāmī continued speaking to Mahārāja Parīkṣit: My dear King, Bharata Mahārāja was a topmost devotee. Following the orders of his father, who had already decided to install him on the throne, he began to rule the earth accordingly. When Bharata Mahārāja ruled the entire globe, he followed the orders of his father and married Pañcajanī, the daughter of Viśvarūpa.
