Last week I was reading Magical Use of Thoughtforms (I think) and while doing a visualization exercise with a cube I decided to paint its faces in different colors and see if I could retain the proper colors and positions.
I painted the cube in the same colors shown in the square in the middle of this book cover (the triangles around the star). The top face I painted black and the bottom white.
The thing is today is the first time I've ever seen this book cover. I think this is related to the Tetragammatron, but I'd really appreciate if someone could tell me or point me in the right direction to find out what this symbol is. I think it's a way kabbalists used to visualize the pronounciation of the true name of god or something like that, with colors, but I'm a total noob and don't know where to begin.
Since it has basically presented itself to me, I think it's same to assume it's important to pursue this.
Also I would like to use this thread to discuss this kind of divination and how to control it, because I've many times been in this position where something I thought I was doing motu proprio was actually something manifesting through my actions.
