In the realm of numbers, Zero is the idea closest to the Ultimate Simplicity: the concept is so simple and profound that the human brain needs to transcend the naturalness of natural numbers to find it.
The zero-fold aspect of the Ultimate Principle is emphasized by the concept of Holy Nullity.
Zero represents the Ultimate Origin that transcends nature; natural numbers represent its manifestations. This can be demonstrated by certain "supernatural" properties of Zero (compared to the "natural" numbers):
Multiply zero by anything - it remains zero.
Multiply or divide non-zero by anything non-zero - it remains non-zero.
Add zero to anything - it changes nothing, for it has no substance at all.
Despite being nothing at all, it gives birth to everything that exists.
