Just know what is happening in your mind - not happy or sad about it, not attached. If you suffer see it, know it, and be empty. It's like a letter - you have to open it before you can know what's in it.
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!
When one drives away the negligent through vigilance, he climbs the heights of wisdom, and can see the suffering masses. Serene, you look upon the lost like one that stands on a mountain sees those that stand upon the plain.
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.
