That shows what awakening means, what sleep means. She was asleep to the Muslim and awake to the one she was going to meet. And he was awake to something else than to the object of his prayer. He was asleep to his object and she was awake. One's heart is where one's treasure is. If it values a treasure it is awakened to it. If it is not awakened to a treasure it may be awakened to some misery. If its treasure is on earth the heart is awakened rather to the earth than to something else.
