A core concept of Buddhism is past, present, and future space and time. It actively focuses on the continuation of Dhamma and builds Maitreya belief after the Buddha's death. Whether it be Mahayana or Theravada Buddhism, Maitreya is mentioned as becoming Buddha in the future by Shakyamuni Buddha. Maitreya Belief has many interpretations, which can be considered in different categories, including. Previous Lives, Future Lives, Bodhisattva Belief, and Chakravartin. The basis for this division is due to Maitreya’s numerous responsibilities in Buddhism. Many uprisings or governments have used the image of the coming Buddha and the Chakravartin taught by Buddha Shakyamuni as a rationale to assist their cause or legitimacy. It's also worth noting that Maitreya was a bodhisattva in Tuṣita before becoming the future Buddha. Tang Dynasty had rich and diverse religions. In particular, Tang Dynasty was a time when Buddhism was flourishing. Buddhism sects showed their talents at that time. There were hundreds of schools of thought, and Maitreya belief was no exception. We utilize Pierre Bourdieu’s sociological theory of fields to explain the religious fields in the middle and late Tang Dynasties, and investigate the reason for the prosperity of the Maitreya Belief, and investigate the reasons for the prosperity of the Maitreya belief, the relationship between religion and society, and the popularity of religions in the middle and late Tang dynasties. Esoteric Buddhism affected society in the middle and late Tang Dynasty. Esoteric Buddhism influenced mainstream Buddhism, Taoism, and the belief imprinted in folks. Although Esoteric Buddhism did not change the core of Maitreya Belief, it added diversity to Maitreya Belief. Religion, society, and believers are all intertwined. Religion's popularity, in addition to social ties, cannot neglect the requirements of believers. And for its various identities, the Maitreya Belief has implemented a number of beliefs. From the standpoint of the believer, we shall investigate the various sorts and purposes of the Maitreya Beliefs. We will consider interactions between Maitreya Beliefs, social interactions, and believers to address the central concept of Maitreya Belief: salvation.
