149:4.2 "Anger is a material manifestation which represents, in a general way, the measure of the failure of the spiritual nature to gain control of the combined intellectual and physical natures. Anger indicates your lack of tolerant brotherly love plus your lack of self-respect and self-control."

48.7.20 Impatience is a spirit poison; anger is like a stone hurled into a hornet’s nest.

110.1.5 All physical poisons greatly retard the efforts of the Adjuster to exalt the material mind, while the mental poisons of fear, anger, envy, jealousy, suspicion, and intolerance likewise tremendously interfere with the spiritual progress of the evolving soul.

131.3.6 Let not anger and hate master you.

131.4.6 Let no man do to another what would be repugnant to himself; cherish no malice, smite not him who smites you, conquer anger with mercy, and vanquish hate by benevolence.

131.6.2 Self is man’s invincible foe, and self is manifested as man’s four greatest passions: anger, pride, deceit, and greed. Man’s greatest victory is the conquest of himself.

140.5.6 Fear and anger weaken character and destroy happiness.

141.3.8 Jesus portrayed conquest by sacrifice, the sacrifice of pride and selfishness. By showing mercy, he meant to portray spiritual deliverance from all grudges, grievances, anger, and the lust for selfish power and revenge.

153.3.5 Do you not know it is from the heart that there come forth evil thoughts, wicked projects of murder, theft, and adulteries, together with jealousy, pride, anger, revenge, railings, and false witness? And it is just such things that defile men, and not that they eat bread with ceremonially unclean hands.

155.1.2 But you who have lived with me well know that anger and wrath are not a part of the establishment of the kingdom of heaven in the hearts of men.

144:2.5 … These stories I tell you to encourage you to persist in praying and not to intimate that your petitions will change the just and righteous Father above. Your persistence, however, is not to win favor with God but to change your earth attitude and to enlarge your soul's capacity for spirit receptivity.

144:2.6 … Genuine faith will remove mountains of material difficulty which may chance to lie in the path of soul expansion and spiritual progress.

91:8.11 God answers man’s prayer by giving him an increased revelation of truth, an enhanced appreciation of beauty, and an augmented concept of goodness. Prayer is a subjective gesture, but it contacts with mighty objective realities on the spiritual levels of human experience; it is a meaningful reach by the human for superhuman values. It is the most potent spiritual-growth stimulus.
