In his book, Harrison makes the case for secularization of Buddhist practices and philosophies. He takes at times a very utilitarian approach to the practice of organizing and structuring the mind, and through this practice is able to take what is useful and discard the rest. He takes particular umbrage to the idea Buddhist idea that life is suffering and to other Buddhist ascetic ideals of celibacy and freedom from want.
Instead, he focuses on the poorly defined idea of mindfulness, which is partly so due to the poverty of the English language and partly due to sheer imprecision of word choice. He notes that by using the newly-coined term, "mindfulness", many use it as a clunky umbrella term to describe aspects of attention, presence, and non-evaluative acceptance... somewhat lazily rolling them all into one jumbled and awkward idea. We should say what we mean when we talk about mindfulness, and going forward, I think it is worthwhile to have a certain strictness of terms and exactness of vocabulary to describe the mind for both scientific purposes and for purposes of clarity.
There were a great myriad of ideas to grapple with in this book and I'm sure I'll be mulling it over for while yet. One to read again.
