Prayer is not designed to inform God, but to give man a sight of his misery; to humble man's heart, to excite his desire, to inflame his faith, to animate his hope, to raise his soul from earth to heaven.
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. He is trying to find me, overcoming a great obstacle -- pushing away, as it were, a huge block of stone weighing a ton. Such a man is a real hero.
