The system of sevens: looking for help in understanding this concept

[tadeus]

There are more references to the "sacred geometry" like the Flower of Life:

The Flower of Life is one of the basic sacred geometry shapes. The Flower of Life starts with the Seed of Life shape: 7 overlapping circles that build outward, forming a flower-like pattern that has been used since ancient times in many cultures around the world. Said to be the basic template for everything in existence; all geometric forms can be found within it, including sacred geometry shapes like the Platonic Solids, Metatron’s Cube, and the Merkaba. The Flower of Life symbolizes creation and reminds us of the unity of everything: we’re all built from the same blueprint.

So the number seven can be seen as a basic "natural constant" of the creation.
