3.433

又六根清淨者，於一一根中悉能具足見色、聞聲、辨香、別味、覺觸、知法等，諸根互用，此義應知。

[Treatise:] "Furthermore, regarding the purification of the six sense faculties: in each single faculty one is fully capable of seeing forms, hearing sounds, discerning fragrances, distinguishing tastes, feeling touches, and knowing dharmas; the faculties are used interchangeably; this meaning should be known."
