I suppose I have a few points, since that color really helps give the eyes a base of operations when scanning the piece:
1. You've written "karma" when maybe "kamma" would be more consistent.
2. For example, the five precepts box goes to five destinations, but otherwise just hangs down there; perhaps the five things being pointed to receive their own color, and then the legend on the side says "that color = precepts". This might help trim out some of the arrows, but may be of limited usefulness throughout.
3. Maybe the various b i u
effects could be used to some effect; the triple gem could be bolded and put in all-caps, freeing up that color for #2 above, etc.
In any event,
