Hindus do not purchase meat from Muslims’ shops. That is impure. [laughter] The same thing: stool this side and that side. They are eating meat, [chuckles] and Hindu shop is pure, Muslim shop is impure. These are mental concoction. Religion is going on like that. Therefore fighting: “I am Hindu,” “I am Muslim,” “I am Christian.” Nobody knows religion.
