An angry person violates the commandment to “Fear the presence of the Al-mighty.” If a person would truly feel that he stood before Hashem, he wouldn’t get angry at Him; he’d be embarrassed and submissive before Him. He would leave his matters to the King’s kindness, because the King is able to fix everything. Furthermore, he should consider that a person angering him is doing so with the permission of Hashem, as Dovid Hamelech said (Shmuel II, 16), “Hashem told him to curse.” (Reishis Chochmah, Anavah 3)
