You are born in an environment that teaches you what to believe, what thoughts to have, and those thoughts are attracting your physical reality. Your environment was chosen by your Inner Being before you were born aiming the expansion of the Universe.
A thought is a vibration. Every human being is a vibration. And the vibration of each one of us is made by every thought we ever had.
In your vibration are active and inactive thoughts, but every thought you thought still exists. If you don’t think about something for a while those thoughts about that something become inactive. When a subject comes with a feeling the thoughts about that subject are active. And every vibration active in you is attracting physical things.
