5 theoretical introduction of Hindu religion in Indonesia

1. Vaishya theory proposed by N.J. Chrome which states that the group Vaishyas (traders) are the largest group that plays a role in spreading religion and Hindu-Buddhist culture. The traders who are already familiar with the Hindu-Buddhist come to Indonesia than to trade them also introduced the Hindu-Buddhist to the Indonesian people. Because the shipping time is dependent on the monsoon, then the time they settled in Indonesia if the wind did not allow them to return. During the Indian traders settle down, allowing the marriage with native women. This is where the influence of Indian culture spread in Indonesian society.
2. Knight theory the promoter C.C. Berg ,explains that the class of knights helped spread the Hindu-Buddhist culture in Indonesia. The Indian knights that helps domina . Assistance provided by the Knights a boost to victory for one group or the warring tribes in Indonesia. As a reward for the victory, was among those who were married with one daughter of the head of the tribe or group that helped. Of the marriage, the knights easily deploy Hindu-Buddhist tradition to the family who married earlier. Further develops the tradition of Hindu-Buddhist kingdoms in Indonesia.
3. Brahmins theory this was put forward by Jc.Van Leur stating that religion and Hindu-Buddhist culture that came to Indonesia was brought by a group of Brahmins (religious groups) who were invited by the Indonesian authorities. His opinion was based on the observation of the remnants of the kingdoms patterned Hindu-Buddhist in Indonesia, especially in the inscriptions using Pallava alphabet and the Sanskrit language. In India it is used only in the language of scripture and religious ceremonies and the only class of Brahmins who understand and master the use of language.
   This reinforces the theory that only the Brahmin caste of Hinduism who understand fully and correctly. The Brahmins who has the right and is able to read the Vedas (Hindu scriptures) so that the spread of Hinduism to Indonesia can only be performed by a group of Brahmins.
4. Reverse Flow Theory This theory was put forward by F.D.K Bosch which explains the active role of the Indonesian people in spreading Hindu-Buddhist culture in Indonesia. According to Bosch, who first came to Indonesia are Indian people who have a passion to spread the Hindu-Buddhist. Because of its influence, it was among the community leaders who are interested to follow his teachings. In further developments, many Indonesian people themselves who went to India for pilgrimage and Hindu-Buddhist learning in India. Back in Indonesia, they are taught in Indonesian society to another.
