7.168

住者如草上之露，日出即晞，眾生妄身亦復如是。然有三意：一、命修短，有纔生即死故。二、比於上界時極促故。三、念念遷謝，即生即滅故。有斯三意故曰少時。

Abiding is like dew on grass, which dries up as soon as the sun rises; sentient beings' false bodies are also like this. However, there are three meanings: 1. Life spans vary in length, for some die immediately after birth. 2. Compared to the higher realms, the time is extremely brief. 3. Moment-by-moment transition, arising and immediately perishing. Because of these three meanings, it says "a short time."
