Axis Mundi

We can’t really as a species conceive of an infinite world. The closest we can come is to identify a centre, and then we feel free to envision the world expanding infinitely beyond that point. We can’t even do the math on infinity without defining a starting point. We can’t express it in even in the most obtuse way.

The world tree is one of those more or less universal presences. No single country or culture originated the concept of the world tree, and what it represents ultimately is the axis mundi. If the culture had no world tree it had a world pillar, more or less, a sacred mountain.
