"His [Siyyid Kazim's] family were merchants of repute. If is father was named Aqa Siyyid Qasim. When twelve years old, he was living at Ardibil near the tomb of Shaykh Safi'u'd-Din Ishaq, the descendant of the seventh Imam Musa Kazim and the ancestor of the Safavi kings. One night in a dream it was signified to him by one of the illustrious progenitors of the buried saint that he should put himself under the spiritual guidance of Shaykh Ahmad-i-Ahsa'i, who was at this time residing at Yazd. He accordingly proceeded thither and enrolled himself amongst the disciples of Shaykh Ahmad, in whose doctrine he attained such eminence that on the Shaykh's death he was unanimously recognised as the leader of the Shaykhi school."
