The regionalisation of India after the end of the Gupta Empire (320-650 CE) led to the loss of patronage and donations. The prevailing view of decline of Buddhism in India is summed by A.L. Basham's classic study which argues that the main cause was the rise of an ancient Hindu religion again, Hinduism, which focused on the worship of deities like Shiva and Vishnu and became more popular among the common people while Buddhism, being focused on monastery life, had become disconnected from public life and its life rituals, which were all left to Hindu Brahmins.
