Ching Hai and her "religious organization" claim that they do not accept donations. This seems like such a nice thing on the surface but just because an organization or religious group says they do not accept donations does not mean that it is true.
A lot of groups get around the donations part by calling it something else like "blessings." Another very popular way to get around it is to sell overpriced items to members. Ching Hai loves to sell overpriced shit to her followers. She starts by giving away plenty of free stuff to get you interested then sells crap at high prices. Urgh, so much money wasted on books that are only useful for keeping a fire going.
I think the only thing Ching Hai loves more than selling useless crap is her restaurant Loving Hut. The restaurant is a franchise meaning that fans of Loving Hut (Ching Hai cult members) use their own money or a bank loan to set up a Loving Hut in their local area. And you bet your ass that the majority of the money goes to Ching Hai in some way or another. Setting up multiple franchises is one of the best ways that the franchise owner (Ching Hai) can make a ton of money. It cost thousands of dollars to set up a franchise. it is also very risky as the business could fail and the person who set it up, not Ching Hai, could lose everything. Meanwhile Ching Hai risks nothing, loses nothing, and gains a lot of money.
