Circle Number 4?

Question

Plain and simple. What does Circle Number 4 mean? It's a lyric from a HIM album. I suppose it means something other than math.

Answer 1

It could mean to actually draw a circle around the numeral 4.
The lyric could also be somehow referring to the fourth circle in a series. I know of no mathematical expression involving that lyric. Perhaps the context of the song will provide a relationship or comparison.

Answer 2

4 is the Supreme Number of the Universe
Within Time Cube, the number four is very significant. It's significant on account of a geometrical principle that is known as the 4-corner-quadrant division.
