If a person's basic state of mind is serene and calm, then it is possible for this inner peace to overwhelm a painful physical experience. On the other hand, if someone is suffering from depression, anxiety, or any form of emotional distress, then even if he or she happens to be enjoying physical comforts, he will not really be able to experience the happiness that these could bring.
Dalai LamaThe fact that there is always a positive side to life is the one thing that gives me a lot of happiness. This world is not perfect. There are problems. But things like happiness and unhappiness are relative. Realizing this gives you hope.
Dalai Lama
