A fighter, a real strong fighter, should always look dignified and calm, and I believe that any expression of aggression is an expression of weakness. A strong person will not be nervous and will not express aggression towards his opponent. He will be confident in his abilities and his training; then he will face the fight calm and balanced.
That the caste system must be abolished if the Hindu society is to be reconstructed on the basis of equality, goes without saying. Untouchability has its roots in the caste system. They cannot expect the Brahmins to rise in revolt against the caste system. Also we cannot rely upon the non-Brahmins and ask them to fight our battle.
