What are the motifs in The Eagle's Gift by Carlos Castaneda?

Time is a recurring idea. The Eagle's Gift deals with time directly only in the final chapters but time as a limiter of efforts and success runs throughout. Time, ultimately, is not something that is measured by the movement of a clock, but is "the essence of attention." It is the "emanations" of an "Indescribable Force," encountered when one steps into one's "other self" or "second awareness," or left-side awareness. The "wheel of time" can be described as a tunnel infinitely long and wide, and furrowed. The force of life confines living creatures to a given furrow and they see only what is in that furrow. They are trapped there.
