Step 25 ~ On Humility
¶17. In the whole universe there is one place that has only once seen the sun, and there is one thought which has often given birth to humility. And there was one day only on which the whole world rejoiced, and there is one virtue only which the demons cannot imitate.
Commentaries suggest the following interpretation:
"One place" = Bottom of the Red Sea.
"One thought" = Remembrance of Death and Crucifixion
"One day" = Christ's Resurrection, Christ's Nativity or Noah's Leaving the Ark
"One virtue" = Humility.
