As always with these small books, I am often surprised by their depth and wisdom that the larger books sometimes overlook, apparently not only did Jesus come to shame proud and worldly men in small books inspired by Him and those who followed Him such as this one, those larger books are put to shame as well, without necessarily being anti-intellectual. This book is a helpful guide to understanding Simplicity toward God, Neighbor, and Oneself.
Every chapter has many levels of insight either on Holy Simplicity itself or as it interacts with things behind itself. I appreciated reading this book, especially since I have on one hand a tendency to make things complex/complicated and on the other hand I tend to have scruples and the author goes straight to the heart of the problem [at least for me] in confronting it and treating this paralyzing obstruction to the spiritual life.
Would I recommend this book? Oh absolutely, the author has done a great job of clearly impressing upon this reader the need for Holy Simplicity in all things (having distinguished it from worldly simplicity) but especially as it relates to the various stages of the Interior Life, which of course is the primary focus. For awhile now I seem to have been living in a state called, "The Dark Night of the Senses" and this book has been a great source of consolation. The Conclusion of this lesson, is of course, self-forgetfulness and the paradoxical statement that in order to attain it you must strive to see only God in all things.
I felt a great resonance when the author mentioned the word, "Spontaneity" in order to better describe Holy Simplicity, which ought to be understood less as impulsiveness to satisfy some lower appetitive drive and more so as something that happens with flow and something organic and naturally occurring. In a certain sense, his writings seem like a more intelligent writing of our contemporary catchphrase encouraging us to "Just Do It."
