What role did Faxian's travelogue play in understanding Gupta society?

Faxian's travelogue, A Record of Buddhistic Kingdoms, is an important foreign account that helps us understand Gupta society. Written by a Chinese Buddhist monk who visited India in the early 5th century CE, it describes peaceful and prosperous conditions, the presence of many Buddhist monasteries, the welfare of people, and how merchants and pilgrims lived. His observations give historians useful evidence about religion, social life and the economy during the Gupta period.
