He was a great scholar and King Harsa of Northern India came to know about him while he was going back to his country. The king made his travel back to China much easier. Hsuan Tsang left India in 643 and reached Ch’ang-an in 645. Back home he was offered a ministerial position but he refused it, as he wanted to complete his religious work. He started translating Sanskrit texts that he brought from India and successfully completed the translation of more than 600 Buddhist texts. Hsuan Tsang’s translations contained some of the most important Mahayana writings.
All through his journey, he kept a journal of his exceptional travel, observations and experiences that later known as the Hsi-yü Chi or Great Tang Records on the Western Regions. At present, this is a single written record of conditions of India and other Western countries at that time. Hsuan Tsang was indeed a great traveler and scholar whose travel to India is still helping historians to find out many answers about Indian civilization then.
