I want to know the answer to the following question:
What did the Guptas promote in their reigns?
All the background I'm provided with is that "The Gupta period marked a watershed of Indian culture: the Guptas performed Vedic sacrifices to legitimize their rule, but they also patronized Buddhism, which continued to provide an alternative to Brahmanical orthodoxy.". Is that enough to answer the question?
Answer: yes
