There is an interesting story in the Nirvana Sutra. One day a young lady of otherworldly beauty visited a rich merchant’s house. She was so attractive that the head of the house asked her if she was a heavenly being. She said she was called Heavenly Maiden of Virtue. Whoever was visited by her obtained anything he wanted, such as gold, silver, lapis lazuli, pearls, elephants, horses, servants, and so on.
