According to legend, this method is divided into nine refinements, each with the same ritual process, but worshiping a different main deity in turn: Taiyi Celestial Venerable of Salvation, Nine Netherworlds Sin-Pulling Celestial Venerable, Venerable Celestial King of Wheel, Venerable of Great Tolerance, Celestial Venerable of the Fire Refining Pill Realm, Golden Palace Incarnation Celestial Venerable, Venerable Celestial Lord of the Red Palace, Carefree Joyous Celestial Venerable, and Venerable of Perfect Treasure Flower.
In the Nine Refinements, souls of the dead pass through pools and fiery marshes, thereby soaring to the Golden Palace and feasting in Yujing.
The book describes this as enigmatic, yet, understood thoroughly, it means not only can one deliver lost spirits, but also revive life by borrowing corpses.
