"One of the most influential discourses on the concept of 'religion' in Vietnam is linked directly with the state. Religion has played a part in legitimizing and reinforcing the state and in rebellions against it. The relationship between 'religion' and 'state' is thus best characterized in terms of 'persistent ambiguities' or 'balanced tension'. It follows that what counts as 'good religion' or legitimate beliefs and 'beautiful customs' is continuously negotiated by the state, Vietnamese scholars, the media and local ritual actors.
This applies particularly to traditions such as the worship of ancestors, legendary heroes and local guardian deities. Even the practices of the mother goddess religion, also called 'Religion of the Four Palaces', which had been illegal as superstition due to central rituals of spirit possession, were revitalized and have become an extremely popular ritual practice."

I can imagine your visiting Heron, Jeanne, balanced upon one of the tents pitched in your back garden, as your followers descend upon you. Something to ponder.
