Polong is a spirit created by magic in Malay mythology.
No one has ever illustrated the figure of the demon but all agree that it is evil and hideous.
Polong is said to have been created from the blood of a murdered person and this blood is put into a bottle for one to two weeks before the spirit is invoked with incantations and magic spells.
After two weeks, the owner will start to hear sounds coming out of the bottle. It is the sound of crying. By then he should cut his finger and drain the blood into the bottle to feed the demon. This is the sign of allegiance and of loyalty to serve the master. The blood which feeds the demon is said to have tied both parties together: one as Master and the other as the servant.
Powers and uses
Like the Hantu Raya and Toyol, Polong is an invisible ghost that can be used by a black magic practitioner to harm someone. Polong has almost a similar role as Pelesit, furious when not fed and will start to harm society. Normally the owner will keep the Polong inside the bottle but unleashes it when needed. People who have been attacked by Polong are left with bruises, a few markings and almost always have blood coming out of their mouths. During possession, a Polong will not listen to anyone except its owner. The owner will come and pretentiously exorcise the demon in order to get money from people. But in some cases a polong which is "sent out" by its owner refuses to free the body that it has attacked. In fact it goes a step further by causing more suffering to the victim. At this stage a Bomoh (shaman) or spiritual leader such as an imam or a priest is called to cast out the polong.
Many of them know that the polong is easily weakened by black pepper seeds (mix with oil and few cloves of garlic). Normally, the shaman will place the seeds on certain parts of the body to cast off the polong. If he is a Muslim, this may be followed by Quranic recitations. The tormented polong will cry and plead, asking for the recitations to cease. It will then confess to the shaman the name of its master. However, it is not uncommon for the polong to name some other person to misguide the pawang (shaman). Hence, the admission must be taken cautiously.
