In religion, deliverance from fundamentally negative conditions, such as suffering, evil, death, or samsara, or the restoration or elevation of the natural world to a higher, better state. Eastern religions tend to stress self-help through individual discipline and practice, sometimes over the course of many lifetimes, though in Mahayana Buddhism bodhisattvas and certain buddhas may act as intervening divine agents. In Christianity, Jesus is the source of salvation and faith in his saving power is stressed. Islam emphasizes submission to God. Judaism posits collective salvation for the people of Israel.
