The following text is for question.

    In Daha kingdom there lived a powerful Brahmin named Sidi Mantra. His son's name was Manik Angkeran. Manik Angkeran liked to gamble. One day, Manik Angkeran could not pay the debt. He asked help to father.

    Loving his son, Sidi Mantra fasted then prayed to the God. A mysterious voice askedhim to meet Naga Besukih at Agung Mount. By ringing a genta, Naga Besukih came and gave gold as well as diamonds from his scales. Soon, Manik Angkeran finished all gold and diamonds. He asked help to his father again. Sidi Mantra came to Naga Besukih. This time, Manik Angkeran secretly followed Sidi Mantra.

    A few days later, Manik Angkeran stole father's genta then came to Naga Besukih. Manik Angkeran got gold and diamonds. But he was not satisfied. Manik Angkeran saw a big gem at the end of dragon's tail. When Naga Besukih turned toward a cave, Manik Angkeran immediately cut off dragon's tail then ran away.

    Naga Besukih was furious then licked Manik Angkeran's footprints. Then he turned into ashes. Sidi Matra was aware of this situation; he begged Naga Besukih to revive his son. Naga Besukih agreed if his tail was back. With magic, Sidi Mantra returned dragon's tail back to normal. Then, Naga Besukih revived Manik Angkeran. 

    Sidi Mantra knew that he could not live with Manik Angkeran anymore. With a magical wand, Sidi Mantra made a line that separated h im from son. There came springs growing into a sea. This is the legend of Bali Strait separating Java from Bali.
