"The Aryans divided their society into separate castes. Castes were unchanging groups. A person born into one caste never changed castes or mixed with members of other castes. Caste members lived, ate, married, and worked with their own group.
"At the top of the caste system were the Brahmin – the priests, teachers, and judges. Next came the Kshatriya (KUH SHAT REE YUHZ), the warrior caste. The Vaisya caste (VEEZ YUHZ) were the farmers and merchants, and the Sudras, were craftworkers and laborers.
"The untouchables were the outcastes, or people beyond the caste system. Their jobs or habits involved “polluting activities” including:
• Any job that involved ending a life, such as fishing.
• Killing or disposing of dead cattle or working with their hides.
• Any contact with human emissions such as sweat, urine, or feces. This included occupational groups such as sweepers and washermen.
• People who ate meat. This category included most of the primitive Indian hill tribes. "
