They are an instrument that Selene Calloni Williams has brought back from her study travels in Myanmar.
Nats are the spirits which live on a mountain called Popa, in Bagan or Pagan (the city of the pagans) in Myanmar. Burmese shamans associate the Nats with the ancestors. Helped by the Burmese shamaness Way Lan Lan, Selene Calloni W. has created a powerful and very effective system of communication with the ancestors through the Nat Cards. Nowadays, Nat cards are a precious instrument used by psychoanalysts and psychotherapists.
