瑜伽師地論略纂 8.149

8.149

論第五解修身觀中云「若緣無識身色於過去有識」等者，此中意，明見死屍於過去世曾有識時，此現屍名外，當有識時名內；緣現有識身未來無識身，內外亦爾。以現有識，未來無識，相似法性、平等法性一相無異，乃至過去亦爾。

In the fifth explanation of cultivating contemplation of the body, where the treatise says, "if one takes as object the form of a consciousness-less body that in the past had consciousness," and so forth: the meaning here clarifies that when one sees a corpse that in a past lifetime once possessed consciousness, this present corpse is called 'external', while the time when it possessed consciousness is called 'internal'; when taking as object a present conscious body and a future consciousness-less body, internal and external are also like this. Because with present consciousness and future non-consciousness, the similar nature of phenomena and the equal nature of phenomena have a single characteristic without difference, and it is likewise even up to the past.
