A man would have no pleasures in discovering all the beauties of the universe, even in heaven itself, unless he had a partner to whom he might communicate his joys.
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.
These joys were so trifling as to be as imperceptible as grains of gold among the sand, and in moments of depression she saw nothing but the sand; yet there were brighter moments when she felt nothing but joy, saw nothing but the gold.
Serving throughout the world is a great missionary force going about doing good. Missionaries teach truth. They dispel darkness. They spread joy. They bring precious souls to Christ.
Do not think only of your own joy, but vow to save all beings from suffering. This is sharing in its highest form and purity beyond all poisons of this world.
