This hagiography places Azar Kayvan, son of Azar Gashasb, and his ancestry back to Sasan the Fifth (cf the Dasatir-nama) then through Sasan the First to the Kayanids, Gayomart, and finally to Mahabad, the figure who appeared at the very beginning of the great cycle of prophecy, according to the "Bible of the Prophets of Ancient Iran," and who seems to be none other than the primordial Adam.
Exhibiting features of a Zoroastrianized Sufi order, this school became known as the Sepassian. Details regarding Azar Kayvan"s life are scanty and are mainly culled from the hagiographical literature of the school. His mother was named Shirin.
Her ancestry goes back to Khosrau I Anushiravan, the Philosopher King.
According to the Dabestan-i-Mazahib, as a young boy Azar Kayvan showed signs of his calling to the contemplative life. Internal references in the biography by his devotees allow us to determine that his residence was at Estakhr (about a hundred kilometers north of Shiraz), where he spent the first thirty or forty years of his life in contemplation and where he assembled his first assembly of disciples.
Around 1570, drawn by the religious revival which was taking place in India around the Emperor Akbar, he left with them to settle down in the town of Patna in the Bihar, where he lived until he died at around eighty-five years of age. Notably among these figures was Shaykh Baha"addin Amili and Mir Fendereski, on whose behest the latter seems to have translated a major Tantric yogic text from Sanskrit into Persian.
According to some scholars, Dastur Meherji Rana, who had influenced Akbar and founded the famous lineage of Parsi high priests at Navsari, was a disciple of Azar Kayvan.
