Buddhist Maitreya
Maitreya is sometimes represented seated on a throne Western-style, and venerated both in Mahāyāna and non-Mahāyāna Buddhism. Some have speculated that inspiration for Maitreya may have come from the ancient Indo-Iranian deity Mithra. The primary comparison between the two characters appears to be the similarity of their names. According to a book entitled The Religion of the Iranian Peoples, "No one who has studied the Zoroastrian doctrine of the Saoshyants or the coming saviour-prophets can fail to see their resemblance to the future Maitreya.
Paul Williams claims that some Zoroastrian ideas like Saoshyant influenced the beliefs about Maitreya, such as "expectations of a heavenly helper, the need to opt for positive righteousness, the future millennium, and universal salvation". Possible objections are that these characteristics are not unique to Zoroastrianism, nor are they necessarily characteristic of the belief in Maitreya.
