Live in the world like a waterfowl. The water clings to the bird, but the bird shakes it off. Live in the world like a mudfish. The fish lives in the mud, but its skin is always bright and shiny.
A devotee who can call on God while living a householder's life is a hero indeed. God thinks: 'He is blessed indeed who prays to me in the midst of his worldly duties.
