成唯識論掌中樞要 2.18

2.18

三喻恒轉中：一、沈浮兩趣間喻；二、逢緣波浪起喻；三、飄流內外物喻。非佛何能止。

In the three metaphors for eternal flowing: 1. The metaphor of sinking and floating between the two destinies; 2. The metaphor of waves arising when encountering conditions; 3. The metaphor of drifting internal and external things. Who but a Buddha could bring this to an end?
