As the days' lengthening becomes perceptible, many candles are lit to hasten the warming of the earth and emphasize the reviving of life. "Imbolc" is from Old Irish, and may mean "in the belly", and Oimelc, "ewe's milk", as this is the lambing time. It is the holiday of the Celtic Fire Goddess Brigid, whose threefold nature rules smithcraft, poetry/inspiration, and healing. Brigid's fire is a symbolic transformation offering healing, visions, and tempering. Februum is a Latin word meaning purification -- naming the month of cleansing. The thaw releases waters (Brigid is also a goddess of holy wells) -- all that was hindered is let flow at this season.
