Wonderful Myth about the Norse World Tree. I love it. Thank-you.

Our coarse reality is surrounded by 9 dimensions in the quanta worlds. The number 9 is about the Higher Mind. It corresponds to The Law of Three (3-6-9) as the building triad of the Universe.

The 9 in the Enneagram as a process tool is about completion. for example: https://the-kai9.medium.com/the-enneagram-as-process-a-primer-aaf9ea44c6c9
