Thank you @dgragonking, I have learned a lot writing this series. In fact I have discovered several things I didn't know:

1. A Bodhisattva's accomplishment of the miraculous harmony (vyuha) of the Bodhi-tree (tree of Enlightenment) consists in that the root of his Bodhi-tree (bodhimanda-druma-mula) is made of gold, the trunk of Vaidurya (lapis lazuli = precious blue stone from India), the branches of all kinds of jewels, the leaves of all kinds of precious things, and the fine fragrance of that tree and its radiance irradiate infinite world systems.

I had no idea about Bodhisattvas and their Bodhitrees. I want to paint this!
