Horse represents partnerships and strength. He also represents power and expanding one's abilities. Horse has innate healing powers. With Bear it is one of only two totems to have innate healing power within.
Horse totems were made by the Zuni to trade with the Navajo who were herders and hunters compared to the more agrarian society of the Zuni. Navajo herders enjoyed having rams, horses and pigs as totems to help increase their herds.
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. (Frank Hamilton Cushing Findings)
