Sufism had enjoyed of penetration and more antiquity like other territories of Iran.Sheikh Zahed Gilani established a Gnostic movement which had some difference with other mystical groups in Iran. However, the base of Zahediyeh's Sufism was on poverty and mendacity, but Sheikh Zahed by political and economic inFluence which had found in Gilan, Shervan, Aran, Azarbayjan was respected by local and Ilkhani's kings. In spite of the great number of Sheikh Zahed Partisans, Shervan's rulers were always shocked with fear and dread. Because Disciples of Sheikh were more than their forces. After joining Sheikh Saffi-al-Din Safiodin Ardebili to him, on the base of the heritage which Sheikh Zahed had carried to him, the mystical method was created by him. It seems, Sheikh Saffi in spite of spiritual motivations and wealth had paid attention to the pecuniary of Sheikh to increase his power by this way. Besides of this issue, Sheikh Saffi, by transferring lordship (being a sayid) from Sheikh Zahed family to himself after getting married Sheikh Zahed's daughter, provided the background of mixed thought of political civil of Iran for his dynasty.
