  Golden spiral
From the bone structure of human beings to the seed pattern of a sunflower to the spiral of a sea shell, the phi proportion is there, underlying all biological structures, seeming to be a geometrical blueprint for life itself.
The other method of determining the Golden Section is by dividing a line segment, AB, at a point C, in such a way that the whole line is longer than the first part in the same proportion as the first part being longer than the remainder.
This spiral is almost identical to the graph of the logarithmic spiral of the phi ratio, known as the Golden Mean Spiral (The difference is that the Fibonacci spiral is a whole number interpretation of the arithmetically impossible Golden Mean spiral, which has no beginning or end.

 Flower of Life - The Golden Mean Spiral and The Merkaba - Article by Ronald L. Holt -
Although the Golden Mean Spiral is principally derived by utilizing mathematics, it is equally mystifying and intriguing to note that this mathematical spiral has additional properties that can be experienced by humans on a profound level that does not require an intellectual understanding of the mathematical principles.
Up until now, in depth material about the significance of the Golden Mean Spiral and how it relates to the merkaba hasn’t been deeply explored even though their interdependence is intricately entwined.
In order to simplify the initial steps to understanding how interlocked and interdependent the golden mean and the merkaba are, we need to have a general understanding and overview of several models that serve as building blocks.
