"In the account of the Tibetan pilgrim Dharmasvamin, who visited eastern India in the years 1234-36, the Vihiira of Uddandapura is mentioned twice as the residence of a Turushka military commander. Of Vikramashila 'there were then no traces left, the Turushka soldiery having razed it to the ground, and thrown the foundation stones into the Ganges' .206In Nalanda, Dharmasvamin observed about eighty small viharas which were damaged by the Turushkas, 'and there was absolutely no-one to look after them, or to make offerings', although two of them were in a serviceable condition."
