"You've got to investigate your mind and watch it all the time. See what it's doing to you. Watch how it controls you. It makes you emotional. It makes you believe something is wrong. It makes you angry. All these things come from the mind.
The idea is to be aware of this. The awareness alone leads you to the light, just being aware of that alone. You don't have to know any book knowledge. Just be aware of what your mind really is. That's how you conquer your mind."
