When it is out, it will be called Beyond the Abyss. Where in chapter 1 it will be focussing on Knowing Thyself and chapter 2 already on the flow state and beyond! The rest of the book is going deeper and deeper inside of yourself while also using even the glow state to go beyond Plus Ultra .
This is also a link, wich will help you further about Glow.
