From a personal experience and the examination of literature, I feel that we cannot take for granted that a dialogue, without information and perhaps without understanding, is possible between any individuals or groups on all levels. So the prerequisite is information.

And there are many people, both Moslem and Christian, who have a good grasp of each others0 conceptions of surrender to God an other principles. But the widespread existence of bias, misinformation and lack of knowledge (…) militate against the effectiveness of dialogue, (…) by the most subtle and one of the most effective of instruments, the subconscious, almost the subliminal, introduction of hostility.

Christian scholars often say that Sufi theories are close to those of Christianity. Many Moslems maintain that they are essentially derived from Islam. The resemblance of many Sufi ideas to those of several religious and esoteric systems are sometimes taken as evidence of derivation. The Islamic interpretation is that religion is of one origin, differences being due to local or historical causes.
