 There are three categories of ritual in Lingbao Daoism . The first is known as the heavenly Golden Register of Rituals , and is carried out to prevent natural disasters . During the Tang Dynasty , this ritual was carried out in honour of the imperial family , but later it could be performed by anyone . The earthly Yellow Register ritual was performed to ensure the dead was at rest . The final type of ritual , which has not survived , was the human Jade Register , which was performed to ensure the salvation of mankind . Of the rituals that have survived , the Golden Register has assumed the role of the Jade register , ensuring salvation and preventing bad weather .
