The shape and substance. The Asuras are very skilled in shape, but have no substance, and hate those who have substance; they want to destroy them. The devil will come very well dressed (probably of saffron), well-positioned socially and with a wide smile on the face, waiting only for the opportunity to destroy all the sacred. On the contrary, even though he is in a seemingly humble position, the sincere devotee has substance written everywhere. A simple song of the sincere devotee, is more powerful than a thousand empty sermons of someone who, as Rupa Goswami explains, is bathing in the caustic urine (deception and hypocrisy) of the great donkey.
