CC Madhya 3.183
loka-gatāgati-vārtā pāba nirantara
“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.
