Pushpagiri, in present-day Odisha, was a prominent ancient centre of Buddhist learning, flourishing near the Lalitgiri, Ratnagiri and Udayagiri complexes.

Nadia in Bengal was a later centre known for Sanskrit and Navya-Nyaya study, not the Odisha Buddhist site.

Nalanda lay in present-day Bihar, not Odisha.

Vikramshila also stood in Bihar rather than Odisha.

Pushpagiri drew monks and scholars and was noted by travellers of the time.

Odisha's Buddhist heritage survives in the excavated monastic ruins around it.
