Hello Peter,
Thanks for your reply. The book is still a little above me I'm afraid, as are the other "spiritual" books that I have read
. I have no idea how much he is taking for granted, I don't even know that what he says is correct per se <shrugs shoulders>. It seems that he mostly makes observations on old quotes and teachings from Kaiso based on his (Sunadomari sensei) experience. It was an interesting book though, one that I will no doubt read again, and certainly food for thought.
