In Daoism, the terms 'mortal body' and 'corpse' are differentiated in a way that reflects the spiritual journey and transformation of an individual. The 'mortal body' is often associated with the physical form that is subject to the limitations and impurities of the material world. It represents the state of being bound to the cycle of birth and death, and is in need of purification and transcendence.
On the other hand, the concept of 'corpse' in Daoism extends beyond the mere physical remains after death. It symbolizes the release from the mortal body and the attainment of a higher state of being. The process of liberation or 'shijie' involves leaving behind the mortal body and being reborn with a body that preserves one's essence but is free from the impurities of the material world.
The distinction between 'mortal body' and 'corpse' in Daoism is thus deeply tied to the religious and philosophical understanding of the human condition and the path to spiritual liberation. It encapsulates the idea of moving from a state of material existence to one of spiritual purity and immortality. This concept is supported by various sources including entries on Wikipedia, academic articles on JSTOR, and scholarly works available on platforms like Brill and Academia.edu, which provide detailed examinations of Daoist beliefs and practices related to the body and its transcendence.
