About This Answer
A questioner with long-standing pain in the leg asks for help so the suffering will go away and the mind can stay wholesome. Ajahn Dtun replies that the body is impermanent and bound to suffering; this is normal. With mindfulness and wisdom we should know this, accept the truth of the body, and try to let go with patience.
He suggests reflecting that if this body were really ours, we could command it not to be disabled and not to feel pain. In truth the body is not under anyone's control. When illness comes we cannot order it to heal, when old age comes we cannot make it young again, and when the body breaks up we cannot order it to stay.
So we should take good care of the body, but teach the mind to understand the truth, accept it, and let go of attachment to the body.
