About: In hoodoo practice, the seven-day candle, sometimes referred to by older practitioners as the "7-day vigil candle" due to its being burned for difficult cases or ongoing situations over the course of seven days, is used while one watches and waits for divinatory signs.
Seven-knob candles generally come in four colors, with the usual symbolism implied (white for blessing or wishing, red for love or sex, green for money or gambling luck, black for destruction or revenge). Carve a brief wish on each knob -- either the same wish seven times or seven different wishes, one per knob. Dress the candle with an appropriate oil. Burn it for seven nights, pinching it out (NOT blowing it out) each time a knob is gone.
