When we have lung, it is essential to try to practice patience. We need to practice not only with the unpleasant sensations related to the lung, but also with other people. When you have lung, you may become easily irritated, and if you simply follow your anger, the lung will become much stronger. Getting angry is the worst thing you can do for your health. It is very helpful to read various books on dealing with anger, especially the patience chapter (chapter 6) of Shantideva's 'Bodhisattvacharyavatara' and related commentaries, for instance, by his Holiness the Dalai Lama and Lama Zopa Rinpoche. Through increasing your understanding you can learn to let go of your anger, rather than following it. Developing patience towards both your lung and other people will bring about greater happiness.
It is important to work wisely with anger, not pushing or mentally beating yourself up because you feel it. Just observe your anger; let it be, let it go. Meditate on compassion. Remember that this anger comes from your karma, and there is no point in getting upset about it. The main thing is not to act out your anger, but also not to supress it. It can be good to talk about it with other people and explain things to them. Explain that you are very sensitive because you are suffering from lung and ask others not be too harsh with you. If you have a problem with someone, talk about it with other people who can listen and help you feel better. Relax, don't look for problems with others, and be positive-look on the bright side of life!
