CC Madhya 8.133

mora jihvā — vīṇā-yantra, tumi — vīṇā-dhārī
tomāra mane yei uṭhe, tāhāi uccāri
Word for word: 
mora jihvā — my tongue; vīṇā-yantra — a stringed instrument; tumi — You; vīṇā-dhārī — the player of the stringed instrument; tomāra mane — in Your mind; yei uṭhe — whatever arises; tāhāi — that; uccāri — I vibrate.
Translation: 
“My dear Lord, my tongue is just like a stringed instrument, and You are its player. Therefore I simply vibrate whatever arises in Your mind.”
