I found that the concept of circle is used in
metempsychosis. Metempsychosis is the teachings of Buddhism and it means that
man’s soul continues to live forever like a wheel of a car after his death by
transforming its form. The meanings of like a wheel and transforming form are
whenever man’s soul comes and goes between this world and the world after
death, it lives with the different body.
I think in metempsychosis, circle means
eternity. I also think the concept of circle lies in our daily life. For example,
when people talk with their companions, they tend to make a circle. I think
this circle represents unity between them. I suppose it means an assembly of
people, too.
I think there are many concepts of circle
around us. I suppose they have various meanings.
