The whole of what we know is a system of compensation. Every defect in one manner is made up in another. Every suffering is rewarded; every sacrifice is made up; every debt is paid.
I think the person who has had more experience of hardships can stand more firmly in the face of problems than the person who has never experienced suffering. From this angle then, some suffering can be a good lesson for life.
Do not be a bodhisattva, do not be an arahant, do not be anything at all. If you are a bodhisattva, you will suffer, if you are an arahant, you will suffer, if you are anything at all, you will suffer.
