Each of us has a certain amount of self-centered tendencies such as desires for domination or pride. When we examine ourselves, we don’t really notice them. But when we see others acting out of a craving to dominate or to boast, for the most part it annoys us.Anger is a blockage and a lock. The Key is the property of Mercy. The Key is in understanding through knowledge, suffering or both.
The Zohar speaks about the force of Receiving and the force of Giving (Malchut and Bina) and the interplay that brings about our world.
Anger is only a result of fear, please read how fear should be perceived here* or if you feel you are ready to deal with it more harshly then understand you need to replace it with complete love*.
