If you are deep into the subject matter and have familiarity with Bob Monroe’s audio materials you may find this book a great read. He is very careful to assure the reader he doesn’t intend to impose a belief system on the reader as an absolute truth or directly claim to have answers. If you are a curious passerby, you may find some of the information a bit wordy and dry, subject matters not embellished for entertainment. It is the closest thing (I’ve read so far) to a 1950’s-70’s era scientist applying scientific method to something ultimately denied by the scientific community.A good portion will be his research notes organized by subject matter in an order designed to make some concepts easy to grasp (since the order of the experiences don’t always yield a great “teaching” order). You will see a lot of his thought process during these tests. It feels very honest without much push to believe him. Different than many other books that claim to teach the neophyte, there is no preditorial hooks attempting to manipulate any emotionally vulnerable readers looking for the secrets or short cuts.Right about the time I felt like this would be another book where the author is just beating around the bush and blowing smoke, he hits with a section all about his step-by-step processes and their importance. Having taken one of the entry level courses from the Monroe Institute already, I felt like this section was a great way to follow that class with “meat and potatos” and I realized so many things I was doing wrong (distractions that inhibit results) and he did such a thorough job to lay out expectations of what success looks like.As he gets into some theories later in the book, stating that it’s a very loose idea that is for consideration, I felt an eery correlation with a few other unrelated bodies of work. It seems like a good fragment of one’s seeking journey as long as it isn’t taken as a singular source of truth. If you combine it with a passionate seeking into many different “underground” subjects you may see this book as aMust Read.My personal addition to this book is that it did take place in a different era. He illustrates a small number of observations correlating the Second Body with electricity and magnetic fields (I think ghost buster traps). In a much more dense day and age with intensely charged magnetic fields, radio frequencies, wifi, Bluetooth etc. I started to get the impression that if you feel suppressed in your spiritual experiences, consider there may be a correlation to the density of computer equipment in your meditation space. A sylvan environment with as little wireless data as possible is my next test.
