There is a set of short stories, poems that give us spiritual lessons. Numerous metaphors help the reader easily learn the lesson.
There is what Dr. Frederick Spiegelberg (professor of Stanford University) said after he heard some stories during the Satsang at Ananda Kutir: "Swamiji, this is just the thing wanted by people today. They would love the humor, but would unconsciously learn the spiritual lesson. The impression made by such teaching would be profound and lasting".
