3.8

釋曰：傳說五於四者，眼等五根各於四事能為增上：一莊嚴身、二導養身、三生識等、四不共事。且眼、耳根莊嚴身者，謂若盲聾身醜陋故。導養身者，眼見、耳聞避險難故。生識等者，發眼、耳二識及相應心所（等者，等取心所也）。不共事者，謂眼能見色，耳能聞聲，用各別故。鼻、舌、身根莊嚴身者，如眼耳說。導養身者，謂鼻臭香、舌甞味、身覺觸，香、味、觸三是段食性，能受用故。生識等者，謂發三識及相應故。不共事者，謂臭、甞、覺，香、味、觸三用各別故。

Explanation: 'It is said that five are [predominant] over four' means that the five indriyas of the eye and so on are each predominant over four things: first, adorning the body; second, guiding and sustaining the body; third, producing consciousness and the rest; fourth, distinct functions. As for the eye and ear indriyas adorning the body: if one is blind or deaf, the body is ugly. Guiding and sustaining the body: seeing with the eye and hearing with the ear avoid dangers and difficulties. Producing consciousness and the rest: generating the two consciousnesses of eye and ear and the associated mental factors ('and the rest' includes the mental factors). Distinct functions: the eye can see forms and the ear can hear sounds, their functions being distinct. The nose, tongue, and body indriyas adorning the body are as explained for the eye and ear. Guiding and sustaining the body: the nose smells odours, the tongue tastes flavours, and the body feels tangibles; odours, flavours, and tangibles are the nature of material food, and they are capable of experiencing them. Producing consciousness and the rest: generating the three consciousnesses and what is associated. Distinct functions: smelling, tasting, and feeling—the three functions regarding odours, flavours, and tangibles are distinct.
