瑜伽師地論略纂 2.63

2.63

「計為我所我及我所」者，我所者，我外所有。我我者，亦是我所，謂計前念我是後念我之我，即前念我是後念我之我也。

Regarding "conceptualizing the self of what is mine and what is mine": "what is mine" is what is possessed outside the self. "The self of the self" is also what is mine, meaning conceptualizing the self of the preceding moment as the self of the self of the subsequent moment—that is, the self of the preceding moment is the self of the self of the subsequent moment.
