Mary seemed to be at a loss as to what is to live. One day the Spirit of Life came to her.
“What do you call the fullness of life?” the Spirit asked. “Oh, I can't tell you, if you don't know,” she said.“Many words are 21 to define it — love and sympathy are those in commonest 22 , but I’m not even sure that they are the 23 ones, and so few people really know what they 24 .”
“You were married,” said the Spirit, “yet you didn’t find the fullness of life in your marriage?”
“Oh, no,” Mary replied,“my marriage was a very incomplete affair.”
