A spiral clock represents the god of infinitely expanding time, Kairos or Caerus. The other god of time is Khronos or Chronos (the god of unaging time) governing limits and boundaries. The two coexist, templates placed over each other. Caerus time is qualitative, and Chronos time is chronologically quantitative.
Maiguru and Tambu are entrapped like this little bird. Maiguru feels entrapped by her marriage. She cannot do things she used to do. And Tambu feels entrapped that she cannot have an education and is kind of trapped in her little village she lives.
