The challenge to a person having an open mind is that the foolish people see his brain as an open top barrel and so they try to just put their rubbish things or thoughts in it than benefiting from him.

An open mind finds every heart an encyclopedia of information to empower his healthy knowledge by picking up the wealthy words and kicking down the filthy thoughts received from every individual's treasure trove.

A noble heart is a window to find an open mind

Mind is still a hidden treasure to explore to benefit. Go for its mining.

Single closed mind is worse than double closed eyes. Closed eyes only cease to see outside world but closed mind stops to see inside world as well.

An ordinary person is one whose life is driven by the mere motivation of making money and sees it as a sheer worth of his birth on the earth.
