1. "Mindfulness in Plain English" - Bhante Henepola Gunaratana. Really liked it & easy to follow.

2. "Peace Is Every Step: The Path of Mindfulness in Everyday Life" - Thich Nhat Hanh. Also good, but found it a bit repetitive. Maybe because I'd already gone through the first one.

Edit: My advice is to read the book so that you enjoy it. After a little bit of practice, you'll find that when you want to sleep, just meditate a little bit. The mind will feel lighter and you will automatically drift to sleep. Don't force yourself to shut off your mind, let it happen gradually. Observe yourself when you drift away. In short, cherish the process, don't take it as an exercise.

Most likely he's referring to this book:

B. Stahl & E. Goldstein, A Mindfulness-Based Stress Reduction Workbook

I'm curious why you say that. Where did you get that reference from?

Looking through chdir's comment history, the only reference to a book regarding meditation and stress is Mindfulness in Plain English by Bhante Gunaratana.

I'm interested in the book chdir's referring to as well.

You're probably right. The book I mentioned is the one I see most frequently recommended as a how-to guide to mindfulness. I have not read Mindfulness in Plain English, but judging by the title it sounds like a similar approach.
