In Daha kingdom there lived a powerful Brahmin named Sidi Mantra. Her sons name was Manik Angkeran. Manik Angkeran liked to gamble. One day, Manik Angkeran could not pay the debt. He asked help to his father.
Loving his son, Sidi Mantra fasted and prayed to the God. A mysterious voice asked him to meet Naga Besukih at Agung Mount. By ringing a genta, Naga Besukih came and gave gold and 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 his father.
A few days later, Manik Angkeran stole his fathers genta and 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 the dragons tail. When Naga Besukih turned toward the cave, Manik Angkeran immediately cut off the dragons tail and ran away.
Naga Besukih was furious and licked Manik Angkerans footprints. Then he turned into ashes. Sidi Matra was aware of this situation and begged Naga Besukih to revive his son. Naga Besukih agreed if his tail was back. With his magic, Sidi Mantra returned the tail back to normal. Then, Naga Besukih revived Manik Angkeran.
Sidi Mantra knew that he could not live with his son again. With his wand, Sidi Mantra made a line that separated him from his son. There came springs growing into a sea. This is the legend of Bali Strait separating Java from Bali.
