bhagavaty uttamaḥ-śloke
bhavatībhir anuttamā
bhaktiḥ pravartitā diṣṭyā
munīnām api durlabhā
bhagavati -- for the Supreme Lord; uttamah-sloke -- who is glorified in sublime poetry; bhavatibhih -- by your good selves; anuttama -- unexcelled; bhaktih -- devotion; pravartita -- established; dishtya -- (congratulations on your) good fortune; muninam -- for great sages; api -- even; durlabha -- hard to obtain.
By your great fortune you have established an unexcelled standard of pure devotion for the Lord, Uttamahsloka -- a standard even the sages can hardly attain.
The term pravartita indicates that the gopis brought to this world a standard of pure love of God that was previously unknown on the earth. Thus Uddhava congratulates them on their unparalleled contribution to the religious life.
