As the one who spent time with Jeff in Serbia, and saw first-hand what he experienced I would strongly suggest that he gets on the 40 day fast in a retreat. He just wasn't happy or excited about anything. It's because he worked on his spiritual self, but still wanted to find that excitement in external and material.
If you are interested in what inspired Jeff to talk about all of this, check out my post about meeting Jeff and hanging out with him in Belgrade.
