Explanation:

Xuanzang (also known as Hiuen Tsang) travelled around India between the years of 630 and 643 CE, and visited Nalanda first in 637 and then again in 642, spending a total of around two years at the monastery. He was warmly welcomed in Nalanda where he received the Indian name of Mokshadeva and studied under the guidance of Shilabhadra, the venerable head of the institution at the time. He believed that the aim of his arduous overland journey to India had been achieved as in Shilabhadra he had at last found an incomparable teacher to instruct him in Yogachara, a school of thought that had then only partially been transmitted to China. Besides Buddhist studies, the monk also attended courses in grammar, logic, and Sanskrit, and later also lectured at the Mahavihara.
