10.83

漸死足臍心，最後意識滅，下人天不生者，明死時識也。言下者，三惡趣也。不生謂阿羅漢也。若頓命終，意識身根忽然總滅。若漸死者，墮於惡趣，識滅於足；若往人中，識滅於臍；若得生天，識滅於心；若得羅漢，識滅亦於心，有言於頂。上來所明皆據最後意識滅也。

"In gradual death: feet, navel, heart; / The mental consciousness ceases last; / In the lower, humans, gods, and the unborn" explains the consciousness at the time of death. "Lower" refers to the three evil destinies. "Unborn" refers to the arhat. If life ends suddenly, the mental consciousness and the physical faculties all cease all at once. In the case of gradual death: for one falling into an evil destiny, consciousness ceases at the feet; for one going among humans, consciousness ceases at the navel; for one gaining birth in heaven, consciousness ceases at the heart; for one attaining arhatship, consciousness also ceases at the heart, though some say at the crown. What has been explained above all relies on the cessation of the final mental consciousness.
