Brahmin
Brahmin (Devanagari: ब्राह्मण, Bengali: ব্রাহ্মণ) is a traditional Hindu society. In the Law of Social Cycle, Prabhat Ranjan Sarkar described four main socio-psychological types, whereby human psychological and physical endowment and social motivations are expressed: the Brahmin, Kshatriya, Vaishya and Shudra.
Sarkar contradicted traditional Hindu social practice and told that no one can be a Brahmin by birth. By birth everyone is a Shudra. After being initiated by a religious teacher, his lifestyle changes and starts to see this world in a new way. This initiation is considered as his second birth.
