The story told us about a couple named Joko Seger and Roro Anteng. They had been married for years but they didn’t have any children yet. They were still on course. To have a child, they prayed to gods everyday and finally Joko Seger had a vision. His wife would be up the spout if he meditated in a cave. However, a lion lived in the cave. Joko Seger came to blows with the lion and he was out for blood. Eventually, he could beat it. Later he meditated in the cave. Joko Seger was meditating. He heard a voice out of the blue.
“Joko Seger, all the Gods agreed to give you children, lots of children.”
'Are you serious? That's very kind of you,' said Joko Seger happily.
'But there is one condition you have to fulfill.'
'Say it. I will beg, borrow and steal as long as you give me many children,' said Joko Seger.
“You will have 25 children but you have to sacrifice one of them when they are adult.'
“I agree,” said Joko Seger without any doubts. He was so elated that Gods would give them 25 children. He thought sacrificing one of them would not be a problem. He would still have 24 children.
At home, Joko Seger told his wife about his conversation with the god. And Roro Anteng could not say anything. After all, her husband had made a promise to Gods. She just hoped that they would never have to sacrifice one child.
Later, Roro Anteng was up the spout. They had a baby. Joko Seger and Roro Anteng were all over the infant. The first baby was followed by others babies. Sometimes, the babies were born twins and other times the babies were born triplets. And the couple finally had 25 children. They were on cloud nine.
When the children were grown up, Joko Seger had a dream. He talked to the God as he was in the land of nod.
“Joko Seger, remember your promise. I'd like you to bring one of your children to the crater of Bromo Mountain. Sacrifice your child there! If you don’t keep you promise, the mountain will erupt and everything will go for a burton.'
Joko Seger woke up from his sleep. He was a bit cheesed off since his dream seemed to be a cloud on the horizon. Reaping the harvest, he then talked to all of his children about his promise.
'No, father. I don’t want to pop my clog,' said the oldest.
“I don’t, either, Father,” said another child.
All of the children declined to be sacrificed. Joko Seger did not have the heart to force them. All of his children were the apple of his eye. The youngest child talked unexpectedly. His name was Kesuma.
'Please let me do it, Father. I love our family and the people of Tengger. But please, commemorate my sacrifice. Every year, please hold a ceremony and provide some offerings to the crater of Bromo Mountain,' said Kesuma.
Kesuma was a very good son. He was compliant with his parents and very kind to other people. All of the villagers loved him. He was kind and always lent other people a hand.
Kesuma went to the crater. He jumped and he was swallowed by fire. Everybody was down in the dump and they were all very thankful to Kesuma. At the hands of him, their place was safe from the eruption of Bromo Mountain.
Until now, once a year the people of Tengger always hold a ceremony to commemorate Kesuma. They bring offerings to the crater of Bromo Mountain.
