few modern Yarsani can read or write Gorani as their mother tongues are Southern Kurdish and Sorani Kurdish, which belong to the other two branches of the Kurdish language family. Some Yarsani literature is written in the Persian language. The older texts are called the Perdiwari texts, which date back to around the 15th or 16th centuries. The texts are called Perdiwari since Perdiwar is where Soltan Sahak had first founded the Yarsani community. The Perdiwari texts are attributed to writers from this first community of Yarsani believers. They include the following texts.

Organisation Khandans or spiritual houses Yarsanism is organised into spiritual houses or Khandans, seven of which were established at the time of Sultan Sahak, and four afterwards, making eleven Khandans in all. The Khandans were established when, along with the Haft Tan, Sultan Sahak also formed the Haft Tawane, a group of seven holy persons charged with the affairs of the outer world. They were Say-yed Mohammad, Say-yed Abu'l Wafa, Haji Babusi, Mir Sur, Say-yed Mostafa, Sheykh Shahab al-Din and Sheykh Habib Shah. Each of the Haft Tawane was charged with responsibility for the guidance of a number of followers, and these followers formed the original seven Khandans, namely Shah Ebrahim, Baba Yadegar, Ali Qalandar, Khamush, Mir Sur, Sey-yed Mosaffa and Hajji Babu Isa.
