yad arcitam brahma-bhavadibhih suraih
sriya ca devya munibhih sa-satvataih
go-caranayanucarais carad vane
yad gopikanam kuca-kunkumankitam
Translation:
Those lotus feet are worshiped by Brahma, Siva and all the other demigods, by the goddess of fortune, and also by the great sages and Vaisnavas. Upon those lotus feet the Lord walks about the forest while herding the cows with His companions, and those feet are smeared with the kunkuma from the gopis’ breasts.
