What is an example of cultural diffusion in India?

An example of cultural diffusion in India is the influence of Buddhism, which originated in the northeastern part of the country and spread to other regions and countries, including Sri Lanka, Tibet, and Central Asia. This diffusion introduced new philosophies, art forms, and practices, such as meditation and stupas, which blended with local traditions. Additionally, the arrival of Persian and Mughal cultures brought new architectural styles, cuisine, and language, significantly impacting Indian culture.
