It is a well known fact that the Nalanda university was destroyed by Bhakhtiyar Khilji and recorded by many historians. The great library was ‘scattered’ during these raids & whatever remaining was shifted elsewhere.
The very fact that the university was founded by Kumaragupta I, a Hindu king and supported by many Hindu kings will be conveniently ignored by this handle. Further ..

The repeated invasions made the monks to flee and settle elsewhere is what made the great university lose its charm. It has nothing to do with ‘Brahmins doing Yajna’
The YouTube ‘historian’ quoted by the handle is reason enough to vouch for the “credibility” of such a thread
