According to Imam Khomeini, courage originates in the strength of one’s spirit, serenity of mind, moderateness, faith, and lack of concern for the vanities of life and indifference to its vicissitudes; whereas anger is the product of spiritual weakness and degeneration, insufficiency of faith, immoderation of character and soul, love of the world and concern for mundane things and the fear of losing the pleasures of life.
