begin by meditating watch yourself in the mirror meditate and look at yourself

"et may vespacha elt tezu"
shadow workings is a tool for getting to know yourself better as this happens watch and observe your subconcious beliefs and thoughts when i did that i was able to read and see them
I had just tried this out. Unfortunately, I did not get any subconscious thoughts or anything of the like. The only interesting thing that occurred was that my face distorted several times and my entire would sometimes become nearly invisible, as well as the surroundings in the mirror. Kinda like how the lines on a sigil disappear.
