Perception and reality must be in balance to see your world as it is. The way that it is and the way that you think it is must be the way that it is. Your Perception is based on people, places and things in your world. Your world is where you and your mind reside.
You have thoughts based on your perception of those people, places and things in your world. You then think your thoughts. Feelings arise from what you think and this is how you will act.
It is how you think and you act the way you think.
