A scientific study of how our brains are wired for spirituality and the correlation between spirituality and depression--very interesting! However, the presentation of these ideas wasn't very good in my estimation. It was slow, hard reading. Not difficult to understand, just boring. But I will say that it is a rare book that I will continue to read in spite of rating it so low. I feel the actual results shown are very important. I guess it is hard to make such documentation into an engrossing read.
