To understand this, let us try to understand....what is a circle?
A circle is a closed line and does not have a beginning and end.
What is a line?
A line is that which is made up of a series of points. What is a point?
A point is what occupies no space.
We say that a series of points make a length, but at the same time that a point occupies no space. If a circle is made up of a series of points which occupy no space, the circle cannot really exist. Still it appears to exist. This is māyā."
