mayi bhaktir hi bhÅ«tÄnÄm
amá¹›tatvÄya kalpate
diá¹£á¹yÄ yad ÄsÄ«n mat-sneho
bhavatÄ«nÄá¹ mad-Äpanaḥ
mayi - unto Me; bhaktiḥ - the nine kinds of devotional service, such as Å›ravaṇa, kÄ«rtana and smaraṇa; hi - certainly; bhÅ«tÄnÄm - of all living entities; amá¹›tatvÄya - for becoming eternal associates of the Lord; kalpate - is quite befitting; diá¹£á¹yÄ - by good fortune; yat - whatever; ÄsÄ«t - there was; mat-snehaḥ - love and affection for Me; bhavatÄ«nÄm - of all you gopÄ«s; mat-Äpanaḥ - the cause for getting Me back.
