Kether, the point
Chokmah, the line
Binah, the curve
In my attempt to relate to the Qabalah in my own terms, mathematics and engineering. I am using this method because I need to relate to what I learn. I have the memory for rote but it makes more sense to me in a context.
Kether is a point, the universe is made of multiple points. Without the point, one cannot have a line or a curve or a shape. Its a scalar quantity but there are infinite scalar quantities, one to infinity.
Chokmah is the line. On the curve, the position of a point can be defined by the equation of a line. A line determines the slope of the curve, whether rising or falling or simply unchanging. A line provides for the beginnings of understanding the form of a shape.
Binah is the curve the provides the shape to a path. Its the map for a shape.
Still working on these ideas but I think I got a good start...
