This is a quote from leaders around the world such as Martin Luther King, President Kennedy, Albert Einstein and many others. But what does that actually mean??
It means that the fact that you can think is your greatest gift and also your most powerful means of creating and realizing your own life.
Since you are the only one who is able to change your thoughts and thus your emotions, you can say that only you have control over the vibration of your body and the height of the frequency your body is in.
This basically means that you can control the frequency of the energy that is constantly flowing through your body and leaving your body to the outside world. And since the powerful law of attraction dictates that you only attract the things with which you are in vibrational harmony, the only conclusion can be that the ‘packet’ of energy you send out at a certain frequency will always come back in some way. the fastest and the least effort.
The universe is flawless and never fails.
You WILL become what you think about.
