Your mind is your worst enemy / your biggest enemy is your own mind.
You will never be free until you free yourself from the prison of your own false thoughts.
Make sure your worse enemy doesn't live between your own two ears.
A lot of the pain that we are dealing with are really only THOUGHTS.
You got to train your mind to be stronger than your emotion or else you'll lose yourself every time.
You are a prisoner of your own mind.
There's nothing in this world that can trouble you as much as your own thoughts.
Monsters don't sleep under your bed, they sleep inside your head.
You are confined only by the walls you build yourself. / The biggest wall you've gotta climb is the one you build in your mind.
Nothing in the world can bother you as much as your own mind, I tell you. In fact, others seem to be bothering you, but it is not others, it is your own mind. ~ Sri Sri Ravi Shankar
