He spent the majority of his life in Yasi, taking the name Ahmad Yasawi. His order is known as the Yasawiyya/Yasavi, and is particularly important in the history of the region, as well as in Anatolia. Their order was known for its disdain for hypocrisy and also the inclusion of certain historic Central Eurasian traditions identified with Zoroastrianism and Manichaeism. The earliest historical record of the Yasavi Order comes from Hakim Ata, and the uncertainty surrounding Ahmad's order stems from the confusion regarding the multiple dates given for Hakim's life and possible direct descent from Ahmad as the second, third, fourth, or fifth generation of the order.
