There is a certain amount of disdain that is placed upon the spider. In a lot of Folk Lore and enchanted stories the spider is considered useless, evil, poisonious, predetorial, selfish. It has been depicted as the Queen of the Underworld in many video games. She is often the first battle boss of RPG games and keeps her children in horrible looking egg sacks that if you burst them, expolde into hundreds of babies looking to feed and live.

  The spider is seen as a lone, rouge, entity that can not be controlled by kings or queens whims, yet full of a wisdom that produces a tapistry as fine as silk. The spider is often depicted carrying the moon between her legs and entrapping all those that come near. The spider, the spider. Even Indianna Jones fear the spider.

What is wrong with a spider? They are the craftiest of creatures you know. They only known to enter a Kings home and receive a welcome for their talents. There are a lot of interesting ideas that have surfaced about the spider: http://www.beliefnet.com/love-family/parenting/2000/09/teaching-tales-king-david-and-the-spider.aspx
The spider might be small, but by taking hold of the work that was nearest, it found its self in "kings palaces". If we take up and accomplish the work that is nearest to us; if we are faithful to do the little and humblest tasks; it is then that we can trust ourselves with greater responsibilities, and greater tasks.
Of Course those ideas have been made in search of finding the good in what is perceived evil. Some of those ideas are rather flat, and fine for children.
I being the Dream Weaver and a weaver of tales find the idea of the Anansi to be more accurate than seeking for justification for the spiders finer points.

 I speak kindly of the spider because I understand the idea of misconeption which breeds mistrust and missplaced accusation before justification can be weaved, displayed, and presented in the finest of arrays. I have listened to many claim how I think too much of myself. Much as the spider is considered small and should remain humble, lest it is squished under the heel of those above it. The spider my friend is such a wonderful creature that as it weaves becomes Lord of the Flies, feasting to it's heart content, living by the laws beyond nature, which imply that only the strong survive. There is a wisdom to be trasured of the spider who's laws are set much higher than it's station.

Imagine that a new palace has just been built. As of yet, no spider has taken her abode in those lofty courts. Now outside, on ground level, a spider down stands surveying the high towering walls above, and considers the wonderful living quarters that must surely exist over those turrets. If you were to scale yourself down the the size of the spider, looking up at the towering walls, how hopeful would you be of getting inside the palace?

It seems like an almost impossible feat! However does the spider despair? Does it stop to try and work out some complex difficult method of catapulting itself over the walls and shortly landing right in the kinds palace? No, without taking shortcuts, the spider simply takes hold with her hands and does the work that lies nearest. Day by day she patiently toils spinning her web and inch by inch the goal comes closer.

Eventually after much toil she reaches the top of the wall and drops over into the courts below. A great task accomplished that previously, could almost have been seen as impossible!

  Such can be achieved by all whom show the same courage of the spider. A master Dream Weaver.
