Mevlana, who is also known as Rumi, was a philosopher and mystic of Islam, but not a Muslim of the orthodox type. His doctrine advocates unlimited tolerance, positive reasoning, goodness, charity and awareness through love. To him and to his disciples all religions are more or less truth. Looking with the same eye on Muslim, Jew and Christian alike, his peaceful and tolerant teaching has appealed to men of all sects and creeds. Every year during 10th and 17th of December in Konya, all the whirling dervishes perform sema which is part of the inspiration of Mevlana as well as of Turkish custom, history, beliefs and culture.
