I’ll start this with I have no real experience with human spirits, so if this idea doesn’t quite work the way I think that is understandable 
the thought came up when I was re-reading the book of five rings the other day, this book, like most philosophy of the time has such a deeper meaning that you can read it multiple times and get different interpretations. With that said, Could I potentially evoke, in this case Miyamoto Musashi, and get an even deeper level of understanding from the book? and would this work with other books, both ancient and more modern philosophers?
