Here are a couple of the phrases I culled from The Xfile's episode, "Blessing Way"

DESCRIPTION: Opens Season 3. Mulder, envisaged dead after Cancer Man and his henchmen close the opening of the boxcar, is found unconscious by his Navajo friends. He consequently goes through the so-called "Blessing Way" chant and is, consequently, healed. After he departs from his helpers to seek the truth, he encounters events which just throw him further and further away from that oh-so elusive notion: the truth.

Albert Hosteen: ...Memory, like fire, is radiant and immutable. While history serves only those who seek to control it; those who would douse the flame of memory in order to put out the fire of truth. Beware of these men for they are dangerous themselves and unwise. Their false history is written in the blood of those who might remember - and of those who seek the truth

ANALYSIS --------

"Memory, like fire, is radiant and immutable". What exactly does this mean to the listener? Let's take a look. Imagine memory as fire:it's bright and radiant. Now, as well as being that, it is immutable - ie cannot be changed.
