The Story of Satyavan and Savitri
When Lord Yama came to procure Satyavans soul, Savitri begged him to grant him life. When he refused, she stopped eating and drinking and followed Yama who carried away her dead husband. Yama said that she could ask for any other boon except for the life of her husband. Savitri asked that she be blessed with children. Yama agreed. Being a PatiVrat (devoted) wife, Savitri would never let any other man be the father of her children. Yama was left with no other choice but to restore Savitris husband to life.
