Many pagan symbols are concerned with the changing of the seasons and a desire for good harvests and fertility. This is not surprising when you consider that the very survival of towns, villages and entire populations depended on the benevolence of the weather, good harvests and production of young animals and children to maintain the population.
In temperate areas, it was during the depths of winter that many families and communities needed additional support so various beliefs and traditions grew up, many of them had practical meaning as well as spiritual.
Pagans believe that every thing has a spirit and by respecting that spirit, even if you are killing something to eat - you will continue to receive bounty and fulfillment. So, if you cut wood, ask the tree spirit first, if you slaughter a cow, ask the spirit for forgiveness and blessing first.
