Either there is momentum on the wisdom side, or there will be momentum on the defilement side. If you were to let go of this wisdom momentum even for a bit, it will take quite a lot to begin again. Beginning again is not that easy. That's why you can't let it stop. Imagine going all the way.

惯性不在智慧这边，就会在烦恼那边。智慧的惯性哪怕有一丝的松懈，也要耗费许多精力来恢复。重新开始并不那么简单。这就是你不能停止练习的原因。幻象一直都在。

个人注解：烦恼还很强大时，恰若逆水行舟不仅必退。奋力追赶还不够，何况懈怠？
