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?""
Jainism
All three religions share concepts and doctrines such as karma and rebirth, and have similar ritual festival grammar, mythologies and monastic traditions. They do not believe in eternal heaven or hell or judgment day. Jainism, like Buddhism and Hinduism, grants the freedom to choose beliefs such as in gods or no-gods, agree or disagree with core teachings, participate or not participate in prayers, rituals and festivals. They all consider ethical values such as non-violence to be important, and link suffering to craving, individual's actions, intents and karma, and believe spirituality is a means to enlightened peace, bliss and eternal liberation ("moksha").
