The caste system has no practical sense in the hinduism.

India or Hinduism, of course, has the caste system or social categorization in general, but it has not any practical sense in particular. Watch Ramayan (Lord Rama & Shabri),  read Vivekananda, and listen Morari Bapu (video attached), then you will understand, for a true Indian such categorization is meaningless.

Earlier selfish Brahmins, then smart British rulers, and now Politicians playing "Divide and Rule" policy in India.
