CC Madhya 4.78

ihā anubhava kaila mādhava gosāñi
tāṅra ṭhāñi gopālera lukāna kichu nāi
Word for word: 
ihā — this; anubhava kaila — perceived; mādhava gosāñi — Mādhavendra Purī Gosvāmī; tāṅra ṭhāñi — before him; gopālera — of Lord Gopāla; lukāna — secret; kichu — anything; nāi — there is not.
Translation: 
How Gopāla ate everything while the food remained the same was transcendentally perceived by Mādhavendra Purī Gosvāmī; nothing remains a secret to the devotees of the Lord.
