CC Madhya 3.4
rāḍha-deśe tina dina karilā bhramaṇa
The word Rāḍha-deśa comes from the word rāṣṭra, or “state.” From rāṣṭra the corrupted word rāḍha has come. The part of Bengal on the western side of the Ganges is known as Rāḍha-deśa. Another name is Pauṇḍra-deśa or Peṇḍo-deśa. The word peṇḍo is a corrupted form of the word pauṇḍra. It appears that the capital of Rāṣṭra-deśa was situated in that part of Bengal.
