Keep in mind that every time you rail and scream at a person you are just projecting onto them a trait within yourself. In order to discharge that energy within you accurately and ruthlessly, so that you may grow into new connections with the world and Spirit, you need to assess your complete circumstances with absolutely no pity, either for others or for yourself. That's when you are on the mark, when you engage energy on that level. The petty tyrant helps to get you there, forces you to work on your own stuff to bring yourself further to light. It is interesting that you bring those up because those are two steps along the path that require working directly with energy.
Fear is a lack of suppleness in the energy body.
This lack of movement translates through the physical body as fear, when it really is just being stuck. You look it straight in the eye and proceed in that direction. From that struggle what you find is that fear is a lack of momentum in your energy body, a lack of fluidity. The more you jolt your energy body with the new experiences you gain by fighting fear, the more you awaken it. Fighting what was a lack of momentum then delivers you to clarity.
