In the spiritual domain, criticism is love turned sour... If criticism becomes a habit, it will destroy the moral energy of the life and paralyze the spiritual force... Whenever you are in a critical temper, it is impossible to enter into communion with God. Criticism makes you hard and vindictive and cruel, and leaves you with the flattering unction that you are a superior person. It is impossible to develop the characteristics of a saint and maintain a critical attitude.
