CC Ādi 4.241

āmā haite guṇī baḍa jagate asambhava
ekali rādhāte tāhā kari anubhava
Word for word: 
āmā haite — than Me; guṇī — qualified; baḍa — greater; jagate — in the world; asambhava — there is no possibility; ekali — only; rādhāte — in Śrīmatī Rādhārāṇī; tāhā — that; kari anubhava — I can understand.
Translation: 
“One more qualified than Me is impossible to find in the world. But in Rādhā alone I feel the presence of one who can give Me pleasure.
