Jainism, an Indian born religion, is one of the oldest religions in the world. In history, the organizational development, religious characteristics, and practice methods of Jainism are closely related to Hinduism and Buddhism, after absorbing the teachings of Brahmanism, those three religions have gained great developments. Jainism, which was born in the Axis Age of human civilization, spread from the Ganges Plain to many other places in the Indian subcontinent under the circumstances of tremendous inequalities of the Brahman caste system, thus was greatly welcomed by the people, especially from lower classes. Although Jainism has not spread to all parts of Asia like Buddhism, even in contemporary India it is only a belief of a very small number of people, but Jainism has been passed down to this day because of its profound teachings, strict practices, and their close social connections. During the British colonial period, a large number of Indians followed the British colonists to cultivate and multiply on the territories controlled by the British empire. Southeast Asia, which has geographical and cultural connections with India, naturally became their first choice. A large number of Indians came to Southeast Asia through land and water. In the grand historical blueprint of the religious development and cultural dissemination of human immigration, Jainism spread from the Indian subcontinent to the other parts of the world is also a magnificent picture; the Indochina Peninsula and the Malay Islands, known as the cultural crossroads, have been deeply by Indian cultures in the history. When Jainism spread eastward to Southeast Asia alongside Indian immigrants in modern times, what kind of intercultural interactions have taken place? In the contemporary world where religion and secularity collide fiercely, how do Jains in Southeast Asian countries balance all of these?
