Siluman is a term used to refer to spirit beings (i.e. spirits, ghosts, jinn). Hence, the mantra siluman is aimed at mastering supernatural powers of the unseen. It is said, that, when a person has mastered the mantra siluman, then s/he can make him- or herself disappear from sight. For this reason, this powerful mantra is believed to enable a person to transform the human body into that a mystic spirit.
Salallahu ngalaihi wasalam,
alahuma kulhu allah,
mimang mimong si Wisakarma tengahing angin,
apipit maya-maya ora katon apa-apa,
kang hima kakalangan petheng dhedhet alimengan si imbar ngemuli aku,
wong sabuwana bloloken ora weruh aku.
