Anytime you react to a person or situation, you do so based on your adopted beliefs or assumptions. You may feel justified because you feel upset or, you feel as though you must vent somehow since events are not going your way. What if none of that matters?
Whenever you get upset, this signals you desire to unload certain kinds of energy. To nurture distressing thoughts and hold them inside is a way you disturb your peace of mind. If a relaxed state of mind is your core state, that is, where you begin and return, then you have reasons why you create the illusion of anything else. Why would that be?
People create hierarchies of importance. These are illusions. One kind of upset is not more or less serious than another. You can evolve to believe the form of any source of distress in your life matters less than recognizing it is an ego strategy to distract you.
Consider you never worry for reasons you think. You are never angry for reasons you think. Every reaction has a lag time from its catalyst. As you learn to follow the thread of your feelings back to reasons why you create them, then your emotional states will no longer control you as they do now. Perception distracts you from meaningful growth.
