Olin is one of three principal shapes or patterns of teotl’s vivifying energies - not a distinct kind of life-energy. Olin is a “how,” not a “what.” The foregoing examination of linguistic, literary, and graphic evidence shows that olin motion-change consists of four-phased pulsating; enlarging and shrinking; bouncing back-and-forth, up-and-over, and down-and-under; oscillating; undulating; and centering motion-change. It is exemplified by the oscillating of the Fifth Sun, the pulsating of a human heart, the bouncing of a rubber ball, the growing and shrinking of a spindle rod with thread, and (as we will see in chapter 8) the undulating of a weaver’s bobbin.
Cyclical initiation, completion, and renewal - in short, transformation within cycles and across cycles - are defined by olin motion-change. Olin motion-change constitutes the biorhythm of the Fifth Sun, the Fifth Era, and all inhabitants of the Fifth Era. It constitutes their essence or heart. It orders, shapes, and centers their existence. It defines the pattern of the existence of the Fifth Age as well as the pattern of existence in the Fifth Age. All things in the Fifth Age are processes, and all processes move-change according to a specific pattern. This pattern is their ohtli, their path. Olin shapes the paths of all things in the Fifth Sun-Earth Ordering as they move through their four-phased life~death cycle. Aztec metaphysics identifies the shape of olin motion-change with the quatrefoil, quincunx, four-petaled flower, four-winged butterfly, and olin glyph. Lastly, olin motion-change unites paired inamic forces - life~death, east~west, descending influence~ascending influence, and order~disorder - within the well-ordered shape of curving, swirling, and oscillating quatrefoils, quincunxes, flower petals, and butterfly wings. This is the shape of olin-generated agonistic inamic unity. This is the shape of olin-generated cyclical completion and renewal. Olin motion-change bounces, curves, swirls, oscillates, and pulsates inamic partners into a single, unified process.
