Zen Mind, Beginner's Mind
Zen Mind Beginners Mind is a simple series of lectures that may help the reader to see reality a bit clearer (it did that for me). Zen Mind Beginners Mind is a simple series of lectures built around the idea, accept nothing till you verify it for yourself. The idea of not accepting anything till you verify it yourself is one of the bright lights of Zen and creates a huge chasm between itself and other paths on spiritual journeys. Shunryu Suzuki is very clear in the book that Buddhism uses this as the foundation of everything that will come after it.
