I am still working my way through this - it has a lot of exercises and thought provoking statements that I am taking my time with. I found the book challenging in all the right ways and it provided a number of channels to unlock creativity and innovation and to explore connections between our inner and outer selves.
When I started to read this book I thought, "oh no it's going to be too Godly." But it wasn't, it was spiritual yes but it was perfect. Not just for writers or artists per se, but for anybody pursuing anything in life. This book has it all.
