pāka-śālāra eka dvāra anna pariveśite
Word for word: 
bāhye — outside; eka dvāra — one door; tāra — of this room; prabhu praveśite — for the entrance of Lord Śrī Caitanya Mahāprabhu; pāka-śālāra — of the kitchen; eka dvāra — another door; anna — food; pariveśite — to serve.

The room was so constructed that there was only one door opening on the outside, which served as an entrance for Śrī Caitanya Mahāprabhu. There was another door attached to the kitchen, and it was through this door that the food was brought.
