You are the core, the center of your world. Without you there is no world for you. Unless you know yourself, you can not know the world, which is your creation. Now you ask every one you meet “How do you do?” But, have you ever asked the question to yourself, “How do I do?” You ask every third person, “Who is he?” But, have you asked the first person, “Who am I?” and searched for the answers.
