He left the Dutch family he worked in and moved to meditate to get purified. For that, the Dutch family called him as Kakek yang bodoh or Stupid Oldman. By his meditation, he became powerful and he used his power to help people. He died in his meditation site. Until today his grave is deemed to be sacred by local people and visited by visitors from cities.
