This quotation is attributed to a chinese buddhist monk who visited india under rule.“the people are numerous and happy; . . only those who cultivate the royal land have to pay [a portion of] the grain from it. . the king governs without . . corporal punishments. criminals are simply fined, lightly or heavily, according to the circumstances [of each case].” —faxian

Gupta is regarded as the most successful dynasty in India.

They are responsible in bringing massive economic growth to indian region along with various development in culture, art, and science. The Gupta also very tolerant and very open minded, which allow people from different cultures and background to come in and exchange their cultures with one another.
