Another Analysis

 An English professor writing an hour-long comment on Hi Ren offers helpful insights on the various personalities that pop up to critique each other's views. (Sorry that this is so badly written; short of time)

I noticed during Ren's monologue, near the bottom of his summing up of his realization that life is not an endless battle between good and evil, but an eternal dance, a never-ending swinging of a pendulum from dark to light and light to dark, and as he spoke these words, his head and shoulders swayed from the light of a lamp, through the dark that followed, then back through the lamplight of the lamp, then the darkness, then light, darkness, light, darkness, and so on and on . . .
