The book arrived on Wednesday and I have almost read through it.
I really like his use of riding a bike as a metaphor - did you ever know anyone who knew how to ride a bike as a result of reading about it? No - you have to do it (and fall off a few times probably). But, then it is ingrained, intuitive, automatic, subconscious.
(A bit ironic writing a book about that subject :-)
His book has helped me make sense of a number of concepts that I have read about in classic martial arts books like "the unfettered mind", "book of five rings", "the life giving sword".
