瑜伽師地論略纂 2.128

2.128

Regarding "those who abide in their final body": It refers to the Buddha's body and all arhats who abide in their final body; there are cases where manifested fire burns the body and it naturally ceases on its own, not being due to the two kinds of harm. When Kālodāyin was killed by another and thrown into horse dung, he subsequently performed supernatural transformations and only then entered final cessation, and so forth at length. The intermediate existence is also like this. For cases like the worm-seer and their kind, such instances are not singular.
