At primary school, in our maths class, we were introduced to the concept of Infinity. I remember the teacher explaining to us that Infinity is an abstract concept invented by mathematicians, and it doesn't exist in the real concrete world where everything is finite. Spiritual work reveals that the opposite is in fact the case. Every natural thing is infinite — there being no end to its unfolding detail — and the finite is very much a man-made condition of his fabricated, unnatural world.
