Khwājagān is a Persian title for "the Masters". Khwajagan, as the plural for "Khwāja", is often used to refer to a network of Sufis in Central Asia from the 10th to the 16th century who are often incorporated into later Naqshbandi and Khalwati hierarchies, as well as other Sufi groups, such as the Yasaviyya. In Firdowsi's Shahnama the word is used many times for some rulers and heroes of ancient Iran as well. The special zikr of the Khwajagan is called 'Khatm Khajagan'.
