Overall they have no rights to use their money, they are heavily taxed, temple money cannot be used for Hindu community welfare but every other religious institutions can do so, even so state give so much funds to minority commission, even temple head and staff are selected by govt and priests are selected with a written exam and not the traditional guru diksha method, average salary of a priest is around 450 rupees or so and he has no rights over the temple money, they can't run schools or gurukuls as missionaries do, they don't have a basic collective structural unit as Sikhs organization, or mosques or churches have, there are so many things. Full state control over hindu institutions.
