I didn't really enjoy this and not because I don't believe in the power of manifestation - but because the idea seems kind of....cult like?
From what it explained, it sounds very similar to the act of sigil-work within Witchcraft. You could argue that these numbers work as sigils, but there's something slimy about the whole thing that I can't put my finger on.
If you want to manifest and meditate with intention, sigil-work offers the same thing. Once you learn how to create and activate them - you don't need any sales pitch or resources with some man's name attached to it.
This book does not provide a full list of Grabovoi codes. However, it does explain what they are and how they can be used. It's just a quick and to the point informative book! Thanks so much to the author!
