The Legend of Tangkuban Perahu
Once upon a time, there lived a beautiful woman named Dayang Sumbi. She had a son named Sangkuriang. One day, Sangkuriang went hunting and killed his own pet dog without realizing it. The dog was actually an incarnation of a god and Dayang Sumbi's husband. When Dayang Sumbi found out what Sangkuriang had done, she was furious and hit him on the head, causing a scar. Sangkuriang fled in anger.
Years later, Sangkuriang returned home, not recognizing his own mother. He fell in love with Dayang Sumbi and wanted to marry her. Dayang Sumbi recognized him and tried to stop the marriage by asking for an impossible task: he had to build a large boat overnight. Sangkuriang almost completed the task, but Dayang Sumbi cheated by faking the dawn. Realizing he had been tricked, Sangkuriang kicked the unfinished boat, which turned into the mountain known today as Tangkuban Perahu.
What is the main reason Dayang Sumbi refused to marry Sangkuriang?
