Sorry George,

I'm not a student of Fethullah Gülen and i do not know much about his background, qualifications etc.

As for the links, yes there are a lot of Arabic terms in some of the material which were originally intended to address students.

However, articles on the theory of evolution (the one i said was for Dawkins) or Shaykh Nuh's description about how he came to Islam (http://www.shadhiliteachings.com/tariq/?act=article&id=5)are straight forward.

Also the following one on kufr (unbelief) should be readable: http://www.shadhiliteachings.com/tariq/?act=article&id=31

I'm just pointing these out because they are all issues that some people have a lot to say about but little if any knowledge. And the information comes from someone with the authority to discuss these matters.
