How does Leslie Marmon Silko use imagery in Four Mountain Wolves?

In Section Two of the poem, the poet introduces us to the "swirling snow wolf." This wolf is not hungry like its predecessor, but rather, an image of cosmic violence, "spilling the yellow-eyed wind / on blue lake stars / Orion / Saturn." The narrator characterizes this wolf with very violent imagery, commanding it to "tear the heart from the silence / rip the tongue from the darkness." This wolf represents the violent power of nature, and the ways in which nature reminds us of the real, physical world when we are contemplating the infinite.
