Here is Meditation Exercise 1 from the Master Key System by Charles Haanel. This is an easy place to start if you have never done any kind of meditation before.
Each meditation progresses a little bit at a time from the previous one. You’re supposed to start with this first one and not skip ahead to the next one before this one has been completed properly.
Meditation Exercise 1
Now make the application – Select a room where you can be alone and undisturbed and sit erect comfortably but do not lounge.
Let your thoughts roam where they will but be perfectly still for from fifteen minutes to half an hour.
Continue this for three or four days or for a week until you secure full control of your physical being.
Many will find this extremely difficult; others will conquer with ease, but it is absolutely essential to secure complete control of the body before you are ready to progress.
