Just so everyone understands what imbolc is sence this is a balkans site and im betting not many pagans around. so here is what the holiday is in short
It is amoung other things the day to celebrate the recovery of the goddess after giving birth.
This season aslo belongs to Brigid, the Celtic goddess who in later times became revered as a Christian saint. Originally, her festival on February 1 was known as Imbolc or Oimelc, two names which refer to the lactation of the ewes, the flow of milk that heralds the return of the life-giving forces of spring. Later, the Catholic Church replaced this festival with Candlemas Day on February 2, which is dedicated to the Virgin Mary and features candlelight processions. The powerful figure of Brigid the Light-Bringer overlights both pagan and Christian celebrations.
This is traditionally a time of purification — clean your house! If you have any Christmas greenery lingering, burn it now.
Make your own Brighid’s crosses and hang them up, especially in the kitchen where her influence can bless your food.
Put out food — cake, buttered bread and milk will do — outside your door: Brighid and her cow walk through the neighborhood tonight, and will appreciate your offering.
Leave a silk ribbon on your doorstep for Brighid to bless: It can then be used for healing purposes.
Meditate upon what you would like to see grow in health and strength this year: for yourself, your family, your community, the Earth, and ask for Bride's blessing upon your prayers
