Absolutely key
This. Book. Is. Key. If you want to meditate--if you don't want to meditate--if you wish you wanted to meditate but you don't honestly--this book is like a sword through the Gordian knot of your feelings about meditation. You don't have to sit, much less in the lotus position; nor close your eyes; nor even "clear your mind." Explodes myths and reminds us that we *already know* how to meditate.
