Meditation is the art of observing your own thoughts. It is the quickest and most widely recognized way to understand your own mind. Even if you are incredibly intelligent and successful, an ability to stand outside yourself is necessary in order for progress. Otherwise, the same habits and tendencies will simply keep repeating themselves. Outside of meditation, it is a good idea to become very strict about what you pay attention to. Do not consume words and images that are not pleasant to your mind. You will have to deal with them in meditation later.
