Number 10 and a line are one. They both represent levelness Their wisdom is balance. When God says creation is perfect, He meant it's at balance or level – needing neither addition nor subtraction. The sum of all existence is an infinite number,, however, the first number of that infinite number is 10. A line represents infinity. Water is the element that expresses levelness. Therefore, - enlightenment is holding fast to what is simple and plain. - up and downs isn't the original nature of reality.
