The Saheb-e-Dilan
In 1875, an eighteen-year old Parsi named Behramshah Nowroji Shroff left Surat (Gujarat, India) for Peshawar (now in Pakistan) in search of employment. According to followers of the mystic philosophy, on Shroff's way there, he met a caravan led by members of the Saheb-e-Dilan ("Masters of the Heart"), who persuaded him to accompany them to their home in the mountains. The Saheb-e-Dilan, according to Shroff, were a group of about 2000 individuals led by 72 Mahgav (Magi) priests, called the Abed Saheb-e-Dilan, who lived in isolation in the recesses of Caucasus Mountains (alternatively, in the Alborz range, around Mount Damavand). Having accompanied the caravan, say his followers, Behramshah Shroff lived with the Saheb-e-Dilan for three years, and so obtained an intimate knowledge of their religious practices and traditions which followed a mystic aspect of the teachings of Zarathustra (Zoroaster).
Upon his return to India, Shroff gathered a following from among the Parsi community, who in due course began calling themselves the Ilm-e-Kshnoom after Khnoom, or spiritual ecstasy, that they believed were embodied in their prayers and ceremonies.
