The flower of life  is a geometric figure that gives access to an initiatory key. It is about the most powerful transmitter of waves of form (more than the pyramid) which makes you profit from the power which it releases. The wave it emits interacts with your electromagnetic field and brings change in your energies. The meeting of the flower of life and semi-precious stones makes it possible to increase the divine properties by working on the subtle planes.
