ei saba grantha kaila gosāñi sanātana
rūpa-gosāñi kaila yata, ke karu gaṇana
ei saba—all these; grantha—scriptures; kaila—compiled; gosāñi sanātana—Sanātana Gosvāmī; rūpa-gosāñi—Rūpa Gosvāmī; kaila—did; yata—all; ke—who; karu gaṇana—can count.
We have already given the names of four books compiled by Sanātana Gosvāmī. Similarly, Śrīla Rūpa Gosvāmī has also compiled many books, which no one can even count.
