There are three fundamental questions in the universe: Who are you? What do you want? Why are you here? However, none if these are quite what they appear.
Most people answer the first question with names and titles, relationships and job descriptions. But that does not tell us anything of ourselves, only what others call us or see of us. Until you can answer that question, without references to outsiders, and describe without words all of what is inside you -- until then, you do know truly know yourself.
And if you do not know your self, how can you know what you lack: needs, wants, desires. If a djinn came to you and offered you three wishes -- or even one -- would you be able to say what would fill the void in your heart? Or would you fall back upon things that others have told you would make you happy?
But even these quandaries seem easy when confronted with the third question. As with the others, it is all to easy to grab the first answer that comes along -- all too convenient to fall back upon religious generalities, job titles and short-term goals. But even answering the question of what path you are on, let alone where that path leads, does not answer why you chose that path in the first place, or how to follow it, or even what you will experience along the way.
