I'm curious - is there a tithe involved in Baha'i? If Baha'is are setting up various social institutions, how are they funding them? Is there a form of personal tithe involved - either mandatory or voluntary - where the individual is expected to help fund Baha'i institutions from their personal finance? Or is it a donor oriented financing - where one or two particular individuals provide the bulk of funds. Or is it an issue of collective and co-operative bodies, where businesses are generated for the sole purpose of creating profits for use in Baha'i projects, rather than personal gain? Simply curious.
