I am referring to the Satpanth sect in this thread, a Gujarati religion which is either a Muslim-influenced sect of Hinduism or a Hindu-influenced sect of Islam, depending on who you ask.
Satpanth is at least partially Nizari Ismaili, or a schism of it, as it is led by the descendants of Imam Shah who play a role not unlike the Aga Khan. The lineage the Harivansh. Oddly enough, Imam Shah is considered an incarnation of Vishnu, and the Quran is considered the fifth Veda, a radical departure from any other sect. There seem to be a variety of syncretisms, with some sects being more Islamic or Hindu than others.
Such an already structure strikes me as open to expansion beyond just being a minor weird sect. The religion already includes a major literary corpus, with a number of hymns and songs all written in Gujarati, so that’s not an issue, and in Gujarat, which is majority-Hindu but with a major Muslim minority, it seems that this religion has a sizeable window for expansion. So, what could be done to expand it?
