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.
Read this and thought of you: Through joy and through sorrow, I wrote. Through hunger and through thirst, I wrote. Through good report and through ill report, I wrote. Through sunshine and through moonshine, I wrote. What I wrote it is unnecessary to say. ~ Edgar Allen Poe
They who shall enter into [the] joy [of the Lord] shall know what is going on outside in the outer darkness. . .The saints'. . . knowledge, which shall be great, shall keep them acquainted. . .with the eternal sufferings of the lost.
You know that kind of quiver that trembles around through you when you are seeing something so strange and enchanting and wonderful that it is just a fearful joy to be alive and look at it; and you know how you gaze, and your lips turn dry and your breath comes short, but you wouldn't be anywhere but there, not for the world.
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.
When you surrender completely to God, as the only truth worth having, you find yourself in service of all that exists. It becomes your joy and recreation. You never tire of serving others.
