CC Madhya 3.183

nīlācale navadvīpe yena dui ghara
loka-gatāgati-vārtā pāba nirantara
Word for word: 
nīlācale — at Jagannātha Purī; navadvīpe — as well as Navadvīpa; yena — as if; dui — two; ghara — rooms; loka — people; gatāgati — come and go; vārtā — news; pāba — I shall get; nirantara — always.
Translation: 
“Since Jagannātha Purī and Navadvīpa are intimately related — as if they were two rooms in the same house — people from Navadvīpa generally go to Jagannātha Purī, and those in Jagannātha Purī go to Navadvīpa. This going and coming will help carry news of Lord Caitanya. In this way I will be able to get news of Him.
