I want to know the answer to the following question:
When did Mahayana sutras start to influence the behavior of mainstream buddhists in India?
All the background I'm provided with is that "It was not until after the 5th century CE that the Mahayana sutras started to influence the behavior of mainstream Buddhists in India: "But outside of texts, at least in India, at exactly the same period, very different—in fact seemingly older—ideas and aspirations appear to be motivating actual behavior, and old and established Hinnayana groups appear to be the only ones that are patronized and supported.". Is that enough to answer the question?
Answer: yes
