haennie,
Great link! As I humbly attempt to give up self will and am hopefully for direction of God's will in my life it has set me on a course ( sober ) of self discovery among other things. The site you shared a link for appears to be exactly what I needed to help with this journey. It's nice to know the question has been asked for thousands of years!
Thank you for taking the time to share this.
