〖锐利的刀〗

当我们说心停止时，是指好像已静止一样，不会到处波动攀缘。譬如我们有一把锐利的刀，如果我们毫无选择地随意乱砍石头、砖块、玻璃之类的东西，刀子很快就会钝掉。我们必须只砍有用的东西。

心也是一样，如果我们放任我们的心，让它乱跑，追随无用的妄念或情绪，心很快就会因为不得休息而疲惫。如果心没有力量，智慧就不能升起，因为没有力量的心等于一颗没有定力的心。

Sharp Knife

When we say that the mind stops, we mean that it feels as if it's stopped, that it does not go running about here and there. It's as if we have a sharp knife. If we go and cut away at things randomly, like stones, bricks and glass, without choosing carefully, our knife will quickly become blunt. We must cut only those things which are useful to cut. Our mind is the same. If we let our mind wander after thoughts or feelings which have no use or value, the mind will become weak because it has no chance to rest. If the mind has no energy, wisdom will not arise, because the mind without energy is a mind without concentration.
