Lord Krishna (His Lilas and Teachings) -Swami Sivananda
“There was formerly in the city of Videhas a public woman called Pingala. I have learnt something from her. Listen to it, O King! One day she put on beautiful dress and waited at the door of her house in the evening, to receive and bargain customers for the night. She invited some persons but sent them away as she thought some other wealthy man would richly pay her. With this inordinate desire she waited sleepless at the door, now going in, now coming out, till it was midnight. Through this anxious expectation of money, she spent the night in a fever of hope, worry and disappointment. She felt extreme disgust for her life of greed and desire which made her unhappy.
