Pramanakoti
Pramanakoti was a beautiful spot on the banks of Ganges, north of Hastinapura (1,128). Duryodhana built a palace here for disporting himself in the Ganges' waters. A huge banyan tree marked that place (3,12). Here Duryodhana poisoned Bhimas food, then bound him and threw him into the river. The Naga tribes living in the vicinity rescued Bhima (1,128) (8,83) (9,56). The Pandavas, in exile, ascended their cars, and setting out from Vardhamana reached the mighty banyan tree (3,1). From here the Pandavas set out for the forests of Kamyaka (3,3).
This place could be in Muzaffarnagar district, where the Ganges turns from an east to west direction to a north to south direction. A small village near this place called Nagal, upstream and on the other (east) side of the river could be the territory of the Nagas who rescued Bhima
