The yin to their yang and/or the bin to their bang?

"The sixteenth century saw the rise of a powerful society based upon a secret cult, in the mountains of Afghanistan - the Roshaniya, Illuminated ones."
"The earliest figure named in the history of the cult is one Bayezid Ansari, of Afghanistan, whose family claimed descent from the Ansar - the 'Helpers', who assisted Mohammed after his flight from Mecca nearly fourteen hundred years ago. As a reward for this service, he stated, his ancestors had been granted initiation into the mysteries of the Ishmaelite religion: the secret, inner training which dated from Abraham's rebuilding of the Temple at Mecca, the mystical Hiram."
"Not far from Peshawar, which is now in the north-west of Pakistan, Bayezid set up a small school, where he carefully coached those who had been initiated by him in the knowledge of the supernatural that he claimed. A period of probation was expected from each candidate, during which he would to into periods of concealment or meditation, known as khilwat - silence. During this time he was to receive the illumination which was emanated from the supreme being, who desired a class of perfect men- and women- to carry out the organization and direction of the world."
