Before answering this question, let us know what is caste and caste ? 1. Tribe - Apatyam Poutrapravriti Gotrang - Panini. Gotra is the tradition of sons, grandsons, great-grandsons etc. In English it means clan, in Bengali clan. In a patriarchal society, the father is the main lineage. According to this custom in the Indian subcontinent , the lineage is determined by remembering the name of the original father. If one says that he belongs to the Bharadwaj clan, then one understands that Maharishi Bharadwaj is the original father of his dynasty of which he is a descendant. They have an inseparable blood relationship. 2. Varna: Chaturvarnyang maya srishtang guna karmabibhagasah. - **** Krishna According to the quality of action, **** Krishna has created four characters. Among the three qualities in it are the people with sattvic qualities - Brahmins , the people with Rajasic qualities, the people with Rikshatriya , the people with Rajah and th mixed qualities, the people with Vaishya and the people with the third quality, Isudra. Their work according to the eighteenth chapter of the Gita - 1. Brahman - Shastra lessons , knowledge, Hindu-Hindu practice , medicine , research , helping in running the state or running the state will work. 2. Kshatriya - State administration , defense, etc. 3. Vaishya - business , agricultural work , cattle, etc. 4. Shudra - care. It has nothing to do with lineage. Because according to the scriptures - Shudra Sanskrat Dwij Uchte at birth. Veda pathanat bhabate biprah brahma janati iti brahman .. That is to say , at the time of birth, everyone is a Shudra , Sanskar makes him a Dvij , in gaining knowledge and in reading the Vedas, one becomes Bipra and if one knows Parabrahma, one becomes a Brahman. It has nothing to do with clan or clan. If there had been , then Rishi Bishwamitra, son of Kshatriya king Gadi, could never have been a Brahmin , Ratnakar, son of Shudra , could never have been Rishi Balmiki. Parashuram, the son of a Brahmin, could never be a Kshatriya , nor could he subdue oppressive kings. Work always depends on merit , not lineage. And the work should be given in the hands of a qualified person. Judge for yourself. :) Thanks.
