Sensation need not be something that I can make a story out of. That is, even painful sensations can just be viewed as phenomena that arise in the mind. When I remind myself that pain is temporary, fleeting and a mental construct, then I can relate to it more as a moment-to-moment experience. I need not be tied to it. I need not embellish on it or create a story out of it. It can be seen for what it is, just one of many momentary situations.
When I am with my sensations, then I can relate to them in a friendlier and more curious, spacious manner. That is to say, they are not my enemies. I am able to see them as something that temporarily arises, then passes away, from one moment to the next. Now, I am no longer identified with these sensations. I can just appreciate them as the workings of complex causes and conditions. This can also most certainly help me to better focus on what needs to be done.
Pain can be a stabilizer of the mind. It can be used as a way to focus on what matters the most. For instance, with pain, we can prioritize the thoughts that are most needed. And we can even use the pain to practice not adding panicked thoughts or judgments to it. If we are able to alleviate the pain, then by all means, we can put our best efforts into it. However, if we can't influence the pain in any way, then it's best not to add anxiety to it. In other words, we don't try to control what is not within our control, but to simply allow it to happen, once we have exhausted all the possibilities. This is one way that we can learn to separate what is in our control from what is not.
