Wow, thanks for the replies.
I have to agree that not all of his images are 'soul' moving. Perhaps his goal and vision are different from normal street shooters.
The reason I really connect to him is because I use to employ his technique using my Sony DSLR. I quickly notice that it is hard to focus quickly to your subject and putting the camera viewfinder to your eye for too long might attract attention. I tried with a 35mm lens and soon found out that I wasnt cut out for it. Too much of an introvert and shyness to actually get close to the subject with a camera.
Beat Strueli does seem to have a knack of picking individuals that I can see. I wonder if any of the muslim he photographes ever caught and confronted him. I personally know the muslim community and they are quite sensitive about being photographed.
