Buddhism developed in India and teaches that suffering can be escaped through following the Buddha's teachings. It spread throughout Asia and the world. The key beliefs are the Four Noble Truths about the nature of suffering and its causes, and the Eightfold Path to end suffering through right view, intention, speech, action, livelihood, effort, mindfulness, and meditation. Following this path can lead to Nirvana, the state of perfect peace and freedom from the cycle of rebirth and suffering.
