The author says this because he is aware of the fact that music appeals to senses. It gives pleasure to every listener. The flute seller does not sell only one kind of flute. He has various types of flutes that represent different customs and culture. The flute seller is a wise sales person. He does not shout out his wares. He plays melodious tunes which fascinate others. Mankind does not have multiple appearances and shapes. It is universal and cosmopolitan. Music soothes everyone’s heart irrespective of their caste, colour and creed. So the author says that to hear any flute is to be drawn into the commonality of all mankind.
