black in color, signify sanctity.
Atop of the cloths should be placed a plate made out of no other material but white porcelain. A mixture of ordinary rice and the glutinous sort should fill about half the plate. This rice mixture is where the cupu with the Kawiyang oil is placed and maintained.
Should the oils be kept indiscriminately without following the above instruction they would soon lose their power. If this occurs, a certain purification ritual must be conducted every Friday and Sunday nights, including full moons to revive the weakening oil. The method is to set up the oil with the lay-out above and then have 3 pieces of red incenses burning together with a lit candle. The incense should be half-consumed before proceeding to the next step. When ready, raise the oil with the plate, together with the cloths above the incense to be purified by the smoke. Have them encircle clockwise around the incense three to seven times. Put the objects down, and then raise just the plate and the oil and repeat the process. This purification should be done for the third time with only the cupu. Encircle the oil vessel 3 to 7 times clockwise around the smoke. While sanctifying the objects with smoke recite the following mantra:
“Jinak ulah raja benila putih nur putih sinar urang gaib”
Once the purification process has been completed the candle may be extinguished but allow the incense be totally consumed.
There is this belief that Kawiyang oil should be taken out of one’s dwelling place when a member of one’s household passes away. Only after the deceased has been buried is it permissible to return the cupu with the oil to its original place within the home.
