You have noticed that the truth comes into this world with two faces. One is sad with suffering, and the other laughs; but it is the same face, laughing or weeping. When people are already in despair, maybe the laughing face is better for them; and when they feel too good and are too sure of being safe, maybe the weeping face is better for them to see.
