What keeps the Gülen Movement’s autonomous networks together so that they are one movement?

The managerially distinct networks communicate their experiences with each other and the with the wider public that they serve. Information, know-how, and patterns of behavior circulate, passing from one network to another, and bringing a degree of homogeneity to the whole. The service-networks thus differ radically from the image of the politically organized actor. Service groups operate on their own, not from one center, although they maintain links to the collective actor through the circulation of information and professionalized people in the fabric of daily life.
