瑜伽師地論略纂 3.56

3.56

第六、生死涅槃難中，「諸行中，此流轉相可得，如於身、牙、河、灯、乘」等者，此意說言：如於身行中，流轉可得，其外法牙、河、燈、乘者雖無有我，亦得流轉，故身流轉何須有我？量云：內身流轉定無有我，有流轉故，如牙、河等。

In the sixth challenge concerning saṃsāra and nirvāṇa, regarding "Among conditioned factors (saṃskāra), this characteristic of transmigration is found, as in the body, a sprout, a river, a lamp, a vehicle" and so forth: this means that just as transmigration is found among the conditioned factors of the body, external phenomena such as sprouts, rivers, lamps, and vehicles, though having no self, also transmigrate; therefore, why must there be a self for the body to transmigrate? The formal inference is: The transmigration of the internal body definitely has no self; because there is transmigration; just like a sprout, a river, and so on.
