I would like to offer some suggestions on how to work with pain in meditation. One way is not to see the pain as a disturbance or as a distraction to meditation. So the pain becomes the object of meditation. When the pain is there, you can try to explore, investigate and find out about the pain. In everyday life, when we have pain what we do is try to get rid of the pain, but by doing that we never learn about pain. So here when pain comes you should consider it a blessing for it gives you an opportunity to work with pain and to understand it. You can explore when there is physical pain whether you can observe and work with the reaction to the pain. Sometimes it is the reaction that is creating the suffering in relation to the pain – by your not wanting the pain, considering the pain as a disturbance, and hating the pain. Having these reactions can create more suffering on top of the pain.
I have discovered that sometimes the pain can have a physical reason, and sometimes certain pains and tensions can be due to a psychological reason. If it has a physical reason, you can work with the pain in this way for some time and then change the posture.
However, in relation to pain you should avoid two extremes. One extreme is pampering the body, for example whenever there is pain you change the posture immediately or try to get rid of the pain. The other extreme is being very hard and severe on yourself, so that you continue to sit without changing the posture at all even when it is very painful indeed. I would suggest therefore discovering a middle way where you learn to be friendly and gentle to the body, to the pain, avoiding being hard and severe towards it, but at the same time not pampering the body. In practical terms, this means to work with the pain when you are sitting and then if necessary to change the posture as I have explained earlier.
If the pain does not have a physical reason, we may have to explore the emotion behind the pain that is creating the pain. Thus in meditation what we are trying to do is not to get rid of the pain but to learn to see even when pain is there, how far we can relate to the pain without necessarily suffering as a result of the pain.
