The same thing happens in life. The heart is the seat of emotions. To understand your heart is to understand your true inner self.
Many people go through life making assumptions about who they are.
We've heard stories of people who suddenly change direction, quitting their job and getting divorced. Knowing yourself is the essence of being alive. If you don't know yourself, you are not living. If you don't know what makes you tick, you're a robot, a puppet, a zombie. So don't wait for a crisis.
