Caste is not a physical object like a wall of bricks or a line of barbed wire which prevents the Hindus from co-mingling and which has, therefore, to be pulled down. Caste is a notion; it is a state of the mind.

I remember watching 'Colombo' a lot with my dad. That was one of the first detective shows I remember watching. And I remember my dad turning to me - my dad loves to turn to me and explain why things are funny. He used to do that with 'Seinfeld' all the time. He did it with 'Colombo', too, set the scene.

To ask questions can become the laziest and wobbliest occupation of a mind, but when you must yourself answer the problem that you have posed, you will meditate your question with care and frame it with precision.
