Oh! Like the circle of life thing. The rings of a tree are like the circle of life, not unlike the minister performing a marriage ceremony. The preacher gets to the part about the symbolism of the ring....... never mind, that doesn't seem to work for nearly 50% of North Americans.
If you think about it, the significance of a circle is the ease in which materials can transfer around the circumference. Compared to the restrictions at the square corners of a square or rectangle. Now a parallelogram or a triangle would be most difficult to maneuver.
I must be the type of person to be living in a circle. I spin my wheels (circle) and never seem to get anything finished. (continuity of perpetual work). But hopefully I am on a spiral up to my ultimate career path.
