The three sages of the East recorded in Taoist classics are: Taiyi saved the suffering Buddha, Dahui Zhenren and Jiuren Zhenren.
Taiyi's classic "Save the suffering and save the suffering" is recommended as a "soul-inducing coffin", which is an important instrument of redemption. Its full name is "Taiyi saves the suffering deity to return to the yellow coffin", which is based on Taiyi's saving the suffering deity, benefiting the real person and saving the suffering real person. Its description was written by Quan Zhen in the Southern Song Dynasty, and Wang Qi really usurped the "Shangqing Lingbao Dafa". It is used to attract the dead. The full names of its characters and gods are as follows: The main picture in the center of the coffin is "Great Compassion and Compassion in the Changle World in the East Pole seeks the sound to feel that it is too painful to save the Buddha", the right column is "Great Compassion saves the suffering real person" and the left column is "Great Compassion benefits the real person". The main picture in the middle is divided into two sections, and the book on the right is "Too Small Return", also in the Southern Song Dynasty. Jin Yunzhong recorded the cloud of the Three Saints in Volume 32 of "Shangqing Lingbao Dafa": "In the East Pole, in the Jade Hall of the Golden Building, I saw Taiyi's nine-color Xia Yunyu taking care of the suffering, taking a bottle of clean nectar and jasper from the throne of Yu Lian, and holding an empty green branch on the right, from two real people, namely Dahui and Yuhe.
