The Kizildeli Bektashi Ocak is an ecol within the Bektashi sufi tradition. Looking at its rituals, apparel, and doctrines, the Kizildeli Tekke must be counted among those tekkes affiliated to Haci Bektas Veli. Kizildeli dervishes believed in the unity of the being, which is observable on their every activity. This study is based on two manuscripts: the first one is Risale-i Lahutiye, a collection by Seyh Ahmed Bedreddin Halveti of the notes of Seyh Sirri Rifai; the second one is called Uyunu'l-Hidaye and written by Giritli Ali Baba, who was a Kizildeli descent. The subject is dealt in terms of both belief and rituals.
