The Tangut state enforced strict laws pertaining to the teaching of religious beliefs and rigorously screened potential teachers. Before he was allowed to teach, a newcomer entering the state from Tibet or India first had to seek the approval of local authorities. Doctrines taught and methods used were carefully supervised to ensure there was no possibility that the Tangut people might misunderstand the teachings. Anyone found to be a fortune-teller or charlatan faced immediate persecution. Deeming it contrary to Buddhist ethical beliefs, the Tangut state strictly forbade religious teachers from accepting compensation or reward for their teaching services.
