Some even become so negative that the thought of another person works in their mind, the thought or the feeling of someone they know or even of someone they do not know works in their mind; they can no longer distinguish between their own thoughts and feelings and those of someone else. But as soon as a man begins to say, "I think like this, but I do not know why," or, "I feel like this, but I do not want to feel so," then he has gone down one step below the normal state of mind. A man who is helpless before his own mind is helpless before everything in the world; and therefore the great mastery is to stand before one's own mind and make it think what one wishes it to think, and make it feel what one wishes it to feel.
