I think one of the defining moments of adulthood is the realization that nobody's going to take care of you. That you have to do the heavy lifting while you're here. And when you don't, well, you suffer the consequences.
There will come a time when everybody will know why, for what purpose, there is all this suffering, and there will be no more mysteries. But now we must live ... we must work, just work!
It is not just a person's physical constitution, their intellegence, their education, or even their social conditioning that enables them to withstand hardship. Much more significant is their inner development. And while some may be able to survive through sheer willpower, the ones who suffer the least are those who have a high degree of patience and courage in the face of adversity.
Each one of us reaps what we ourselves have sown. These miseries under which we suffer, these bondages under which we struggle, have been caused by ourselves, and none else in the universe is to blame. God is the least to blame for it.
Now this, monks, is the noble truth of suffering: birth is suffering, aging is suffering, illness is suffering, death is suffering; union with what is displeasing is suffering; seperation from what is pleasing is suffering... in brief, the five aggregates subject to clinging are suffering.
Who shall blame whom, who praise whom? Whom to seek, whom to avoid? I seek none, nor avoid any, for I am all the universe. I praise myself, I blame myself, I suffer for myself, I am happy at my own will, I am free. This is the Jnâni, the brave and daring. Let the whole universe tumble down; he smiles and says it never existed, it was all a hallucination. He sees the universe tumble down. Where was it! Where has it gone!
...morally speaking, there is no limit to the concern one must feel for the suffering of human beings, that indifference to evil is worse than evil itself, that in a free society, some are guilty, but all are responsible.
