CC Ādi 11.33
nityānanda-nāme yāṅra mahonmāda haya
Puruṣottama Paṇḍita, a resident of Navadvīpa, was the eighth gopāla. He would become almost mad as soon as he heard the holy name of Nityānanda Prabhu.
It is stated in the Caitanya-bhāgavata that Puruṣottama Paṇḍita was born in Navadvīpa and was a great devotee of Lord Nityānanda Prabhu. As one of the twelve gopālas, his former name was Stokakṛṣṇa.
