If there is suffering, then it's best to accept it, because it won't go away just because you pretend it's not there. If there is joy, then it's best to accept that too, even though you're afraid it might end one day.
Joy is the wild card of life; it supersedes every other formula for success. If you can find a way to create joy, you can rise beyond all external factors. If you can play at whatever you are doing, you are the master of your life.
Those who show pity and are always ready to help during times of trouble are seldom the same ones who rejoice in our joy: when others are happy they have nothing to do, they become superfluous and lose their feeling of superiority, and so they easily show their displeasure.
But that had been grief--this was joy. Yet that grief and this joy were alike outside all the ordinary conditions of life; they were loopholes, as it were, in that ordinary life through which there came glimpses of something sublime. And in the contemplation of this sublime something the soul was exalted to inconceivable heights of which it had before had no conception, while reason lagged behind, unable to keep up with it.
