1. Actual mercy

    …we also must know what actual mercy is. To give a sick man something forbidden for him to eat is not mercy. Rather, it is cruelty. Unless we know what mercy really is, we may create an undesirable situation. If we wish to show real mercy, we will preach Krsna consciousness in order to revive the lost consciousness of human beings, the living entity's original consciousness.
