Another significant factor was the absorption of Buddhist practices and ideas into Hinduism, which led to a syncretic culture where the distinction between the two religions became increasingly blurred. Over time, many Buddhist practices were assimilated into Hinduism, and the Buddha was even incorporated as an avatar of the Hindu god Vishnu in some traditions.
The economic and social changes in Indian society also contributed to Buddhism's decline. As religion became more monastic and disconnected from lay life, it failed to adapt to the changing needs of society. The wealth accumulated by Buddhist monasteries made them targets during invasions, and without strong lay support, the religion struggled to recover from these setbacks.
Despite its decline in India, Buddhism found new life beyond its borders. It spread to Central, Southeast, and East Asia, where it adapted to local cultures and continued to flourish. In modern times, there has been a revival of Buddhism in India, with movements aiming to rediscover and re-establish the teachings of the Buddha in the land of its birth.
The decline of Buddhism in India is a testament to the dynamic nature of religious traditions, showing how they can transform, adapt, and sometimes wane in response to changing historical circumstances.
