"Suffering is our best teacher because it hangs onto us and keeps us in its grip until we have learnt that particular lesson. Only then does suffering let go. If we haven’t learnt our lesson, we can be quite sure that the same lesson is going to come again, because life is nothing but an adult education class, If we don’t pass in any of the subjects, we just have to sit the examination again. Whatever lesson we have missed, we will get it again. That is why we find ourselves reacting to similar situations in similar ways many times."
