When did Maitreya become the Tathagata?

Maitreya (Sanskrit:? Maitreya (Pali: Metteyya), literally translated as cishi, transliterated as Maitreya and Maitreya, is the successor of Sakyamuni Buddha and is often called Maitreya Buddha. He is one of the eight great bodhisattvas of Mahayana Buddhism and is often called Ayutthaya Bodhisattva in Mahayana classics. According to legend, Maitreya Buddha was born in a Brahmin family in the south of Tianzhu and was a disciple of Sakyamuni Buddha. He often practices Bodhisattva Taoism, and now lives in the inner court at the rate of heaven fighting. When the time is ripe, he will inherit Sakyamuni and come to the world to become a Buddha.

Maitreya, Maitreya's Sanskrit surname, is a common Brahmin surname, and its root comes from Maitr in Sanskrit, which means kindness. When Xuanzang went to India to study, he saw the original Sanskrit and translated it into Maizoriya. But before Xuanzang, the early translators in the post-Han and Three Kingdoms periods all saw Buddhist scriptures obtained from the Western Regions and translated them into Maitreya. Modern scholars believe that Maitreya may be related to Mithra, which is popular in Central Asia, and is similar to the sound and meaning of Messiah.
