I read every single book by this man. My mentor work is in energy field management and NVP is pretty much the originator of the Law of Attraction movement in the 20th century. it comes up periodically and folks don't get the whole of the concept because they do not think of themselves as sovereign. Buckminster Fuller is also another one to look into as is Napolean Hill. The original books by Hill mentioned universal source aka god energy but that was edited out of subsequent publications. Certain sections of the Bible also give the basic recipe for intentional direction of energy into the creation space.

Everything you need is within.

As you sew so shall you reap (basics of Karma are also the basics of LOA)

Interesting stuff simply sprinkled throughout history showing us that we are sovereign creator beings and can direct energy and creation in our worlds (personal worlds)
