 Both the Mantra and the nembutsu were often incorporated by medieval Buddhists at one time or another, often in the same service.A common practice for the Mantra of Light was to sprinkle pure sand, blessed with this mantra, on the body of a deceased person or their tomb, based on teachings expounded in the Sutra.The belief was that a person who had accumulated much bad karma, and possible rebirth in Hell would be immediately freed and allowed a favorable rebirth into the Pure Land of Amitabha Buddha.
