The blackdeva's flying shard magic: take the twig of a 榎 jia tree (Catalpa Bungei), the twig pointing north-west; twist it to the shape of a buckwheat grain, write the Sanskrit letter भ on each of its three faces, place it before thedeva, recite his spell a thousand times then cast the charm into the house of a prosperous person, saying may his wealth come to me.
