“unhappiness about being unhappy”

​our current mental-hygiene philosophy stresses the idea that people ought to be happy, that unhappiness is a symptom of maladjustment. Such a value system might be responsible for the fact that the burden of unavoidable happiness is increased by unhappiness about being unhappy.

“the size of human suffering”

If a certain quantity of gas is pumped into an empty chamber, it will fill the chamber completely and evenly, no matter how big the chamber. Thus suffering completely fills the human soul and conscious mind, no matter whether the suffering is great or little. Therefore the “size” of human suffering is absolutely relative.
