Bear-  Guardian of the West. The bear is associated with great strength, power,  healing and self-knowledge. He is the great protector, the "sacred  bear" He is a spiritual guide and also carries within him supernatural  powers. Bear is a powerful healing fetish. All bear fetishes are  powerful but the white bear is the most powerful medicine bear. 

There are six sacred directions, each  guarded by a prey god (North -  Mountain Lion; West - Bear; South -  Badger; East - Wolf; Above -  Eagle; Below - Mole).  It is believed that  the hearts of the great  animals of prey are infused with a spirit of  magic over the hearts of  the animals they prey upon.  The prey gods are  given high rank among  the gods.  Because of this, their fetishes are  greatly esteemed as  mediators between people and the animals they  represent.   

Power of the Fetishes: The Zuni people feel  that the power of the  Zuni  fetish lies within the heart of the Zuni Fetish, much like the  power of  the animal the fetish represents.  It is believed that the  hearts of the  great animals of prey are infused with a spirit or  medicine of magic  influence over the hearts of the animals they prey  upon.  The "breath of  life" derived from their hearts whether near or  far never fails to  overcome a game animal.  The breath of the powerful  prey animal  overcomes the weaker animal, piercing it's heart and  causing it's limbs  to stiffen and the animal itself will lose it's  strength.  The roar or  cry of the beast of prey is fatal to the game  animals which hear the  cry.  It charms their senses as does the breath  of their hearts.  Since  the mountain lion lives by the blood or "life  fluid" and flesh of the  game animals, and by these alone, he is endowed  not only with the above  powers, but also with peculiar powers in the  sense of sight and smell.   Moreover, these powers as derived from his  heart, are preserved in his  fetish, since his heart still lives, even  though his person has been  changed to stone.
