Pandarapura
Sri Caitanya-caritamrta
CC Adi-lila
CC Adi 10.106, Translation and Purport:
The ācārya Śaṅkarāraṇya was considered the forty-eighth branch of the original tree. From Him proceeded the subbranches known as Mukunda, Kāśīnātha and Rudra.
It is said that Śaṅkarāraṇya was the sannyāsa name of Śrīla Viśvarūpa, who was the elder brother of Viśvambhara (the original name of Śrī Caitanya Mahāprabhu). Śaṅkarāraṇya expired in 1432 Śakābda (A.D. 1510) at Sholapur, where there is a place of pilgrimage known as Pāṇḍarapura. This is referred to in the Madhya-līlā, Chapter Nine, verses 299 and 300.
