How did hinduism impact the gupta empire?

Well, let's see here...

Hinduism is based on peace and prosperity, and it's a religion that is based on truth and reality which is completely odd in my opinion.
The Guta Empire lasted approximately for two hundred and thirty years (230 years).  

The religion and the empire correlate together because the religion is what brought everyone together.  With the golden age occurring during some of the time during the presence of the empire, Hinduism flowered and spread throughout the empire (and throughout the rest of India); the religion brought people together and even separated them so the actual beliefs could shape India the way it is now.
