How to Meditate

Writing instructions here on how to meditate would be pointless given all the great information that's already available. 

There's a great set of audio instructions and a posture guide with pictures available here:

For those who want to dig deeper I'd recommend Steve Hagen's book Meditation Now or Never.

If you're interested in learning the Zazen style of meditation you can also look for a local Zen center. Most of them offer free instruction at least once a month.
