The world brings neither good nor evil by itself. He is indifferent to man. Everything that happens around us is just a reflection of our own thoughts, feelings, desires, actions. The world is a big mirror.
All people, events, situations sent to us are our reflection. And they are sent so that we, looking and interacting with this, correct our mistakes, and when we correct them, these people, events, situations, either also change, or leave our life.
