Your inside is a reflection of your outside. Your inner world is a reflection of your outer world.
Your outer world and the things you create into your reality is a mirror of what you believe and have created inside of you.
You were born without a belief inside of you. That which has been done to you or by you, with or without your consent, both “good and bad” things, have buried themselves inside you. They are then manifested as your reality outside of you.
If you are angry inside of you, you will find angry people in your life. They are mirroring your denied anger back to you. If you are peaceful inside of you, you will find yourself in the company of peaceful people mirroring peace back to you.
