CC Madhya 13.23
tāṅra saṅge krīḍā kaila nibhṛte vasiyā
For fifteen days the Lord had remained in a secluded place with the supreme goddess of fortune and had performed His pastimes with her.
The fifteen-day period of anavasara is also called nibhṛta, in honor of the solitary place where the supreme goddess of fortune lives. After living there a fortnight, Lord Jagannātha took permission from the goddess of fortune to leave.
