Brahmajala Sutta (Theravada)
In the second part, the Buddha explains the major beliefs of ascetics in India. He begins by saying, ""Monks, there are other things which are very deep (profound), very hard to understand, very difficult to perceive, so holy and sacred, unreached by means of mind, so subtle, that they are only to be understood and experienced by the wise. These things were perceived clearly, seen clearly and were discarded by the Tathagata, and by this act based on the truth that people praise and revered Tathagatha. What are those things?""
Freedom of religion in India
India is one of the most diverse nations in terms of religion, it being the birthplace of four major world religions: Jainism, Hinduism, Buddhism and Sikhism. Even though Hindus form close to 80 percent of the population, India also has region-specific religious practices: for instance, Jammu and Kashmir has a Muslim majority, Punjab has a Sikh majority, Nagaland, Meghalaya and Mizoram have Christian majorities and the Indian Himalayan States such as Sikkim and Ladakh, Arunachal Pradesh and the state of Maharashtra and the Darjeeling District of West Bengal have large concentrations of Buddhist population. The country has significant Muslim, Sikh, Christian, Buddhist, Jain and Zoroastrian populations. Islam is the largest minority religion in India, and the Indian Muslims form the third largest Muslim population in the world, accounting for over 14 percent of the nation's population.
