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.'
An essential condition of listening to God is that the mind should not be distracted by thoughts of resentment, ill-temper, hatred or vengeance, all of which are comprised in the general term, the wrath of man.
