But with all its forms, the Sufi idea also has the formless ideal of worship. The form is to help the one who can be helped by seeing the form, because all education is an education of names and forms. If there were no form and no name we would not have learned them. The form is only suggestive of what is behind it, of the one and same truth which is behind all religions. Therefore this service is a teaching at the same time, yet every Sufi is free to take up a form or not to take up a form. A Sufi is not bound by a form; the form is for his use, not to make him captive.
