Very hard work. No, not this book ,but what it expertly tries to teach you to do – meditation. One clue is in the title - Unknowing. Meditation is partly about forgetting self and knowing everything, and there is a lot to learn about letting go. It's not just sitting quietly and relaxing as you might either drift of to sleep (although I was told at a day retreat hosted by the World Community for Christian Meditation that if you fall asleep it's probably because you need to do so) or let miscellaneous mind rambling take over, but really opening ourselves to God. The book is split into short 'chapters' (hardly long enough to be described as such) so you can think on the lesson of each one before moving on. Then when you've finished, you'll probably want to go back to sections for encouragement and refreshment, and keep the book to refer back to as the going gets tough. The book was originally written in the 1980's, but in a way it's almost more important today as the pace of life has accelerated even more and the very moment when we say we have less time to spare, and we are becoming more self-centred, is when the value of meditation becomes greater. My only criticism of the book is the type setting as the print is far too black and densely set for comfort.
