Many people in Shamanism like to wear a medicine bag around their neck filled with saced objects.
These objects may be stones, crystals, hebs or twigs.
These objects connect the Shaman with their special powers.
It also establishes a relationship with other levels of reality.
The pouch may be circular, made of cloth, with cord around the edge and gathered up at the neck.
A Power Bundle is a larger version.
It may be spread on an alter, burnt in the case of herbs or shaken in the case of a rattle.
A Crane Bag is similar to a Power Bundle.
It derives from Celtic beliefs.
The Crane Bag contains the Shamans tool kit.
