"To neglect your own mind, that's like to neglect your consciousness. That’s like to give up all hope of joy and happiness, really. You're the only one that can discover for you the meaning of anything. What it means to you. By that, I don't mean intellectual meaning. I mean, what it means, how it makes you feel. You have to see whether you really are happy or not. Whether you really are sad or not. And you have to investigate what goes through your mind."
