To someone struggling to figure out what their purpose in life is, the suggestion that, somewhere inside of you, you know is exasperating. Everyone, at one time or another, asks the questions of: Who am I? What do I want? These questions are often about finding passion, purpose, or happiness. How do you find your center?
Proceed by sitting quietly, away from the distraction of television and radio, electronic media of all kinds, and conversation with others. Enjoy a sunset, gaze into the flames of a fire, watch clouds drift by, listen to the rustle of the leaves and see where your mind goes.
Write upon waking. Write three pages, by hand of anything that comes into your mind, without censorship. After several weeks, go back and see what you have written. Those thoughts that flit through you brain onto the page that you have forgotten as soon as you went on to the next thought, will show you what you are tolerating, what you choose to ignore, what you are struggling with, and what your deepest desires are.
Yes, the answer is at the center of your being. Be still, and listen.
