Krishna is pictured in Hindu symbology with a crown of peacock's feathers, playing the flute. Krishna is the idea of divine love, the god of love. And the divine love expresses itself by entering in man and filling his whole being. Therefore the flute is the human heart, and a heart which is made hollow, which becomes a flute for the god of love to play. When the heart is not empty, in other words when there is no scope in the heart, there is no place for love. Rumi, the great poet of Persia, explains the idea more clearly. He says the pains and sorrows the soul experiences through life are holes made in a reed flute, and it is by making these holes that the player makes out of a reed a flute.
