Out of four major castes in Hinduism, human made Brahman caste is superior one according to Hindu “Sruti” literature. In different types of Hindu rituals, they chant or reflect their commentaries on four Vedas. There are many types of Brahmans in the Hindu society having different surnames. The surnames are also creations of the humans. Each Vedic school had having its own Brahmans with specific texts of each Veda. Sources say that there are 19 types of Brahmans associated with four Vedas. Rig Veda, Sham, Yajur and Atharva Veda associate with two, six, ten and one respectively.
The Brahmans glosses on mythology, philosophy and rituals of all the Vedas. Rig Veda rely on the effeteness of truth contain in the hymns (mantras). The people who composed Vedas gradually developed their semi nomadic life style and began to settle permanently. In a later date, they developed Vedanta, law, astronomy, geometry and linguistic concept of Karma (deeds) in Sanskrit. Panini is one of the examples of it. He is the founder of Sanskrit language. All the Indian languages have originated from the Sanskrit language. It was the royal language in India according to Hindu scriptures. They have divided the life in to four stages like (1) Chilhood(Shishab),(2) Brhmachary (Youth),(3)Grihasta(family life) and (4) Sanyasi (Saint or Rishis) or Aranyak. This refers to earlier tribal kingdoms during the later Vedic period.
There are thousands of languages all over the world having various religions. The languages have evolved stage by stage with various modifications of their respective linguistic researchers. Our ancestors have taken lot of pain to express their thoughts in oral as well in writing scripts. The Linguistic researchers know it very well. Hence, there should not be any feelings based on languages, tribes, religions, caste, color and race. Above all we are humans under one roof though lived separately having separate entity consequent upon growth of human populations. In my concept, human tribe is one and scattered subsequently to various tribes and religions, and the shape of humans based on their types of food, climate condition and place of shelter.
However, I am a Brahman, but I do not believe the caste based religion, color and creed. Simply I know that I am a human and my caste is humanity.
