SB 10.47.68
evam sabhajito gopaih
krsna-bhaktya naradhipa
uddhavah punar agacchan
mathuram krsna-palitam
Translation:
[Sukadeva Gosvami continued:] O ruler of men, thus honored by the cowherd men with expressions of devotion for Lord Krsna, Uddhava went back to the city of Mathura, which was under Krsna’s protection.
Purport:
The word krsna-palitam indicates that even though Uddhava became quite attached to the land of Vrndavana, he returned to Mathura because Sri Krsna was personally displaying His transcendental pastimes there.
