Who am I?” Maybe you’ve never even asked yourself this question. You might think you already know who you are. Unfortunately, however, it’s likely that you don’t know who you are at all. And if you don’t know your real identity, you’re in trouble. You’ll spend your life in a kind of dream state—you’ll falsely identify yourself as something or someone you aren’t. Then, on the basis of this false identification, you’ll determine the goals of your life and the purpose of your existence.
