Koleduvane is the most important ceremony performed after midnight on Christmas Eve. According to Bulgarian popular wisdom, if carol singers fail to pass by, "the year will be barren" and everything will go wrong. That is why every family prepares to welcome them as the most cherished guests.
With the carol singers, fertility and well-being enter people's homes. The Christmas blessing is the ritual gift upon which the well-being of each family and the whole community as a whole depends. If the carol singers do not perform their ritual actions at the time determined by tradition, the year and the land would remain fruitless and barren. For nothing can be born without being conceived, for barren is what is not fecundated. With its magical rite, the carol company symbolically "fertilizes" the earth in order to guarantee bereket (good harvest), to keep the crops healthy, and to multiply the livestock.
