Brother puffyp-There are several techniques and you will have to find one that works for you. The technique I describe below seems to help most people calm the mind and find their center.
Start by taking 15 - 30 minutes each day to just close your eyes and control the body. Choose a place that you can sit comfortably and undisturbed. After you have mastered this for a week, you can start on trying to calm and center the mind.
Using breath seems to help most people. First focus your thought on the feelings of the air flowing in and out of your nostrils. After you have been able to do that for several minutes add the feeling of the chest and abdominal movement. At first your thoughts will bounce back and forth between your nose and your chest/abdomen; but with practice, you will be able to think of both sensations at the same time and that is the first big step in calming and centering your mind.
Perhaps MEDITATIONS ON MASONIC SYMBOLISM by John R. Heisner will also help you on your path. I have enjoyed it.
Enjoy your journey, Patrick
