Brahmin is a part of the caste system in Hinduism. A Brahmin is a teacher, doctor, scholar, or religious person. The Brahmins were the highest in all four castes. They are called Dwij because they are twice born people who guide others toward enlightenment. They were fire-priests. The Brahmins developed in the Aryan society by how powerful the people in this caste were. The people in the caste were all famous kings and popular leaders in the Aryan society. The Brahmins' society grew into the Aryan society around 1600 BC. The Brahmins have right to arrange prayer and rituals and they can do the works of warriors in their absence. Parashurama was a Brahmin by birth, but throughout his life, he was a warrior whose job was to protect Dharma. Brahmins are vegetarians. There are many subgroups in Brahmins. Bengali and Kashmiri Brahmins eat fish but they do not eat any other meat. Brahmins of South Indian origin practice cross-cousin marriages and maternal side cousin marriages. North Indians do not practice any cousin marriages and it is taboo for them. South India is not Aryan. Some people of South India Brahminized through adopting it from North India just as they adopted Jainism.
