When one is ashamed of an abominable action, one naturally becomes down-faced. Diti came to her senses after the abominable sexual intercourse with her husband. Such sexual intercourse is condemned as prostitution. In other words, sex life with one’s wife is equal to prostitution if the regulations are not properly followed.
