This book is awesome http://www.amazon.com/Mindfulness-Pl...dp_kinw_strp_1
It talks about mindfulness meditation which is focusing on nothing but the breath. It's helped me a lot. If I stop meditating regularly I start having road rage and being more irritable. There's other kinds of meditation, like mantra meditation, guided meditation, I started off with a CD "Guided meditation for healing" by Deepak Chopra and I like it but I also really enjoy sati (mindfulness) meditation. And also hate it, lol, it's hard for me to sit still and focus, my mind races but that's the point of it, is to keep gently bringing your attention back to the breath when you realize you've wandered.
