You see this really clearly when you focus on the breath. The breath is always there in the body, and if you look carefully you”ll discover that it has many levels. It”s like looking up in the sky: Sometimes you feel a breeze coming from the south, but you look up in the sky and see a layer of clouds moving east, and another higher layer of clouds moving west. There are lots of different layers of wind in the atmosphere and, in the same way, there are lots of different layers of breath in the body. You can choose which ones to focus on. 那就是业的原则的另一个寓意: 你可以改变你的行为。如果体验的某些部分随选择和造作而定，你可以选择改变。这一点，在你专注气时，可以看得很清楚。气在体内始终存在，如果你仔细观察，就会发现，它有许多层次。就好比观测气象: 有时侯，你察觉一阵轻风从南方吹来，然而抬头观天，看见一个云层在朝东移动，另一个更高的云层在朝西移动。大气层中存在许多层次不同的风，同样地，身体内部存在许多层次不同的气。你专注其中的那些，是可以选择的。

　　It”s like having a radio receiver: You can choose to tune-in to different stations. The radio waves from all the nearby radio stations, all the different frequencies, are all in the air around us. There are radio waves from Los Angeles, radio waves from San Diego, even short wave radio waves from who-knows-where, all over the place. They”re going through this room right now. They”re going through your body right now. And when you turn on the radio you choose which frequency you want to focus on, which one you want to listen to. The same with the body. You sort out, of all the possible sensations, just one type of sensation to focus on: the breath-ness of the breath. Wherever you feel the sensation of the in-and-out breath most clearly, you focus right there. Now some of us have a radio we haven”t taken very good care of, and as soon as we tune it in to one station it slips over to another. So you”ve got to keep tuning it back, tuning it back. 这就像是无线电接收器。你可以选择调收不同的电台。来自附近所有电台的电波，所有不同的频率，都存在于我们周围的空中。有来自洛杉矶的电波、来自圣迭哥的颠簸、甚至有不知哪里来的短波，到处都是。它们现在正在穿过这间屋子。它们现在正在穿过你的身体。当你打开收音机时，你选择想专注的频率，想聆听的频率。身体也同样。你在所有可能的觉受中分捡，单单挑出一类觉受——气的气性——专注于它。你在哪里最清晰地感受到出入息，就把注意力定在那里。我们有些人有一台保养不佳的收音机，一调到某个频率，它就滑到别的频率上。因此，你不许不停地把它往回调、往回调。

　　But the problem isn”t just the tuning. It”s what you do with the sensation once you”ve tuned-in to it. Again, you can focus on the breath in a way that makes it painful, or you can focus on it in a way that makes it comfortable. You”re not faced just with the given-ness of the breath. What you do with it can make it more or less painful, more or less comfortable. To continue the analogy, it”s like having a volume control on the radio: You can turn it way up loud so that it hurts your ears, or you can turn it way down soft so that you can hardly hear it at all. But as you get more skillful with your volume control, you get a sense of what”s just right so that you can adjust the level and the pressure of your focus for maximum enjoyment. 不过，问题还不单单是调频。还有一旦调进去了，对那个觉受做什么的问题。再一次，你专注气的方式，可以令它痛苦，也可以是令它舒适的。你面临的并非仅仅是前定不变的气。你对它做什么，可以使它多痛或少痛、多乐或少乐。延续先前的比喻，就好像收音机上有个强度调纽: 你可以把它调得巨响，以至于耳痛，或者，你可以把它调得极弱，以至于几乎听不见。不过，随着你对强度的调节熟练起来，就会懂得什么是恰到好处，这样就可以调整你专注的层次和力度，获得最大的享受。

　　As you get tuned-in more and more precisely, you discover there are other subtleties as well. Again, like the radio, when you really get tuned very precisely onto the frequency, the static goes away and you can hear subtleties in the signal that you couldn”t hear before. You can play with them, turn up the treble, turn up the base, whatever you want. So even though the radio signal is a given, you can do a lot with it. That”s the element of kamma in your meditation right now: It”s what you”re doing with the breath. 随着你的调入越来越准，你还会发现其它的细节。再一次，以收音机作比方，当你极其准确地调到那个频率上时，杂音消失了，你就可以听见讯号中过去听不见的微妙之处。你可以操纵它们，把高音成分调响，把低音成分调响，随心所欲。因此，尽管那个无线电讯号是先决的，你对它可以有很多作为。那就是你当下禅定当中业的因…
