 ramayam asa gokulam

Uddhava remained there for several months, dispelling the gopis’ sorrow by chanting the topics of Lord Krsna’s pastimes. Thus he brought joy to all the people of Gokula.

The great acarya Jiva Gosvami comments in this regard that Uddhava, during his stay in Vrndavana, certainly took special care to enliven Krsna’s foster parents, Nanda and Yasoda.
