Priests of Holy Grail - Free Reiki Attunement
Priests of Holy Grail is a powerful Reiki system for psychic protection and exorcism by Ömer Volkan Akkuş. The system uses Catholic symbols to banish negative entities - but you do not need to be Catholic to utilize the system (see note below). The examples in the manual deal with demonic possession but this energy can also be used for more "everyday" cases of psychic attacks. Upon receiving the attunement, you might experience a wall of protection around you by the priests themselves.
