I see your point and don't disagree with it. However reading is a part of experience and along with self knowledge can be a great help in understanding others. The golden rule can only be lived out of a lived experience of inner pain, suffering than makes us understand others.
Books can give us the language to be able to 'name' what it is that we are going through. People who don't learn from others, though whatever means is what leads to becoming self centered and insular, which only adds to the burden. Using the language and metaphors of ones spiritual path will allow for more connections if ones faith traditions is understood thought study and experience. Too many people give up their faith traditions too easily I believe. Any path, if kept too will be difficult, it is better to have deep roots as well as the ability in dealing with 'unknowing'.
For instance studying about depression can help someone going through it......knowledge from books along with personal experience is invaluable.
