俱舍論記 1.222

1.222

「自身名內至或約處辨」者，內外門。自身成就名內，不成就及他身非情名外。故《集異門足論》第十一云「云何內色？答：若色在此相續，已得不失，是名內色。云何外色？答：若色在此相續，或本未得、或得已失、若他相續、若非情數，是名外色（已上論文）。」或約處者，處謂十二處。五根名內，六境名外色。

"One's own body is called internal ... or determined according to the bases": the gate of internal and external. What is possessed by one's own body is called internal; what is not possessed, as well as other bodies and inanimate things, are called external. Therefore the *Saṅgītiparyāya-śāstra*, fascicle 11, says: "What is internal matter? Answer: If matter is in this continuum, already attained and not lost, this is called internal matter. What is external matter? Answer: If matter is in this continuum, but either originally not attained, or attained and then lost, or in another continuum, or inanimate, this is called external matter (above is the treatise text)." Or "according to the bases": "bases" means the twelve bases. The five sense-bases are called internal, and the six sense-objects are called external matter.
