瑜伽論記 2.255

2.255

第五建立染淨難中，此意說言，如於外物雖無有我，而有災橫損緣藥等順益名為染淨，內身亦爾，雖無有我染淨義成，故汝計不應理。

Under the fifth, the objection concerning the establishment of defilement and purification: the intended meaning here is that just as with external objects, although there is no self, there are disasters and adverse conditions of harm or medicines and so forth that bring benefit, which are called defilement and purification; the internal body is likewise: although there is no self, defilement and purification are established; therefore, your tenet is unreasonable.
