The Bajang Child Swinging the Moon (141)
In front of Rahwana, Sumantri felt that returning to Jatisrana was so beautiful. He became undeterred by death, because for him death and life were no longer apart
Following Darmawati's death, when he bade farewell as he was about to go to the battlefield, he had said, "I will return to Jatisrana." At the time he didn't really understand what he was saying, despite an urge to say it. With the demon of death standing before him, he really understood now what "I will return to Jatisrana" meant.
It turned out that with those words he was actually invited to experience his rebirth that would usher him to pick up his death. So, he felt self-justified that, on the battlefield where death awaited, he forced himself to wear the clothes he had worn when he lived in Jatisrana.
