The Desatir or Dasātīr (دساتیر lit. "Ordinances"), also known as Dasatir-i-Asmani, is a Zoroastrian mystic text written in an invented language. Although purporting to be of ancient origin, it is now generally regarded as a literary forgery, most probably authored in the 16th or 17th century by Azar Kayvan, the leader of the Zoroastrian Illuminationist sect. Its Neoplatonic ideas have been strongly influenced by the 12th-century philosopher Suhravardi, and have only a tenuous connection to mainstream Zoroastrianism.
