The Mind Illuminated presents the progress of meditation in 10 stages, with exercises, what to expect, and common problems and ways to overcome the hindrances at each stage. It is a really good meditation guide, and I've read it a lot.
The book introduces a new set of vocabulary for meditation and has spawned a subreddit dedicated to the book, where one can easier relate their meditation experience with each other using a shared framework.
The meditation practice is a Buddhist one, a Theravadan Buddhist one, and the practice is called "Samatha Vipassana" which combines Vipassana, the laser eye focus, dry practice, searching for truth or insight, with the Samatha, the practice of feeling joy and entering Jhanas. Functioning as a sort of lubricant of the Vipassana, making the insight easier to stand, in a way.
I suppose no review of this book is complete without the recognition that Culadasa, some time ago, was the target of some controversy when he was, as a married man, accused of having slept with prostitutes. Although this might cause concern, I was more concerned about his immature way of handling the situation and eventually making an announcement stating that he didn't know why he did it and that he was going to seek a psychologist.
Sexual misconduct of meditation teachers is not a new thing. People tend to excuse them as "merely human," and say that we ought not to give them a "guru" status, and it doesn't change the value of their teachings.
That's where I'd disagree, because the fact that "he didn't know what came over him" and that he wanted to see a psychologist, completely invalidates his theory of mind and mindfulness, presented in the book.
Culadasa laid out in the later chapters of the book, how eventually the different sub-minds will unite into one mind, and the conflicts of the mind will cease. Whereas before mindfulness, Culadasa says, the mind is dragged by horses going in all different directions. Only mindfulness will unite the will of the horses, and all parts of your mind will come into consciousness, one goal. On top of this, the magic of mindfulness will cause all of your impurities to uprooted.
Here's a quote from the book:
"The unification of mind in śamatha is temporary and conditioned. However, the unification around insight is far more profound, and it's permanent. When temporary unification around a shared intention fades, each sub-mind operates as a separate entity, constrained by, and at the mercy of the mind system as a whole. Therefore, individual sub-minds strive to preserve their autonomy, and, as much as possible, direct the resources of the mind system toward their individual goals. Yet after insight, the various sub-minds become unified around a shared insight into impermanence, emptiness, suffering, no-self, and interconnectedness. From this flow a corresponding set of shared values: harmlessness, compassion, and loving-kindness. Now, each sub-mind operates as an independent part of a much greater whole, working for the good of that whole. This allows each sub-mind to do its job effectively, without running into fundamental conflicts with other sub-minds. When enough of the mind system has undergone this transformation, we're able to function as an individual person while simultaneously perceiving ourselves as part of an indivisible and inconceivably greater whole."
I suppose that someone who had gone through all this unification work suddenly has no idea why he had sex with prostitutes, you might very well conclude that his theory of mind is plain and simply incorrect.
Considering how the book's subtitle says "Buddhist Wisdom and Brain Science" and how there's virtually no brain science in the book, it serves as a forewarning that Culadasa does not have great respect for honesty, even though it probably made him sell more books since neuroscience is so hot these days.
(great meditation tips tho.)
