This was the first book I read by Thich Nhat Hanh. I had heard a lot about him prior to this. When I read the book, I could easily see why there is so much excitement about him and his works. He writes in a very clear, very accessible style. This book is a commentary on the Heart Sutra. The Heart Sutra is said to contain the essence of Buddhist teachings. I would recommend any book written by Thich Nhat Hanh!
Just reading the first couple paragraphs of this book was like, "aaaahhh..." Completely relaxing. The writer's message and style is simple yet poetic, and very important--how to not be afraid. This is the first Buddhist book I have ever picked up, being that I had only studied Buddhism from the classroom/historical aspect, and never viewed it in any way as something I would actually connect to or practice in my life. Now I can. This book is refreshing, short, easy to read. I would recommend it to anyone.
