Meditation

I have never tried to meditate, but really want to! I've read and heard so much about the effects and importance of meditation that now I'm ready to learn. The only similar experience I have had by now were the 5 minutes of relaxation at the end of yoga classes, and I liked it.
They say it's easy, but something doesn't let me chase away the thoughts. I'll be trying to quieten my mind and reach that feeling of oneness.
