sidati sakhi mama hrdayam adhiram
yad abhajam iha na hi gokula-viram
madhava-catu-patalam api lesam
nalokayam arpitam uru-haram
pranamantam ca dayitam anuvaram
hanta sanatana-gunam abhiyantam
kim adharayam aham urasi na kantam
Refrain: Friend, because I did not worship the hero of Gokula my heart is now shattered.
(1) I did not listen to even a fragment of the advice of my friends or the sweet words of Lord Madhava.
(2) I did not see my beloved repeatedly bowing down and offering a precious necklace.
(3) Why when He approached me did I not hold myself forward to my eternally virtuous lover?
