大毘盧遮那成佛經疏 2.5

2.5

The sūtra says: “An internal self.” There are those who impute that within the body, apart from the mind, there is a separate nature of the self, which is able to move this body and perform all activities. The refuter says: “If it is so, the self is impermanent. Why is that? Because if a dharma is a cause or produced from a cause, all are impermanent. If the self is impermanent, then the retribution of sin and merit would all be cut off.” Such various arguments will be explained at length in the appraisal section.
