The Shijie ritual, a Taoist practice, involves several core elements:

1. Cicada Metaphor: This symbolizes the shedding of the old body for a new one, much like a cicada sheds its skin.
2. Body Preservation: The body is treated to prevent decay, aiming to maintain it for the resurrection.
3. Ritual Suicide: Some practitioners may engage in self-sacrifice to achieve a higher spiritual state.
4. Resurrection: The central belief is that the practitioner will be reborn into a new body.
5. Escaping Difficulties: The ritual may also serve as a means to overcome worldly challenges or suffering.

These elements are deeply rooted in Taoist philosophy and the pursuit of immortality. For more detailed information, refer to the Wikipedia page on Shijie (Taoism).
