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?""
Indian religions
Hinduism, Buddhism, Jainism and Sikhism share certain key concepts, which are interpreted differently by different groups and individuals. Until the 19th century, adherents of those various religions did not tend to label themselves as in opposition to each other, but "perceived themselves as belonging to the same extended cultural family."
