Visuddhimagga XIV-48

Vuttampi cetaṃ dhammasenāpatinā –

正如法将（舍利弗）说：

Ñ(XIV,48): And this is said by the General of the Dhamma:

‘‘Yena cakkhupasādena, rūpāni manupassati;

Parittaṃ sukhumaṃ etaṃ, ūkāsirasamūpama’’nti.

由于眼净， 随观诸色，

既小而细， 如虱之头。

Ñ: 'The sensitivity with which he sees a visible object

Is small and it is subtle, too, no bigger, than a louse's head'(?).
