A scroll of Sutra of Salvation can reveal the affairs of one's previous life.
The revolving lantern of Corpse Body Buddha, in a certain sense, is neither a Buddha nor the lifetime of a person, but rather a negative embodiment of numerous monks and practitioners of the Western Heaven Buddhist realm, a delusion mercilessly cut down.
It is like garbage casually discarded by the monks, wandering outside the four corners of the world.
Besides seeing those stripped malign roots, Xu Qing also witnessed countless desires for greed, anger, and ignorance wandering without a physical body, seeking new forms to inhabit.
The monks casually cutting and banishing these evil corpses, meanwhile, remain outside, enjoying the peace brought by the Buddha realm to them.
Due to the influence of these banished worldly corpses filled with the three poisons, various wrathful auras such as killing, stealing, sexual misconduct, and deceit breed in the murky world.
