The Buddha is not a god. In early Buddhism, Siddhartha Gautama possessed no salvific properties and strongly encouraged "self-reliance, self discipline and individual striving." However, in later developments of Mahayana Buddhism, notably in the Pure Land (Jìngtu) school of Chinese Buddhism, the Amitabha Buddha was thought to be a savior. Through faith in the Amitabha Buddha, one could be reborn in the western Pure Land. Although in Pure Land Buddhism the Buddha is considered a savior, he is still not considered a god in the common understanding of the term.
