How-To Become Calm and Centered
Make your magic more effective by building emotional and psychic intensity and focusing clearly on your goal.
Sit while holding the stone and listening to the music in a quiet room at home, or in the outdoors if the weather is nice. Breathe deeply and rhythmically. Begin inhaling through your mouth, then exhaling through your nostrils with a long, steady humming note. With each exhalation, make the note smoother and draw it out longer. Breathe your tension and anxiety into the stone. When you feel calm and centered, put the stone on the ground, open the circle and walk away. The stone will dissipate the tension into the Earth to be transmuted; if you wish, you can retrieve the stone in a day or two for later use.

OR

Lay down with your arms by your side.
Begin breathing as though you are pretending to be asleep. Breathe in deeply, hold it for 5 seconds, and breathe out, hold for 5 seconds, breathe in again and repeat the pattern.
Focus on your feet. Feel them relax, feel the tension leaving you. Then focus on your legs, your stomach, your arms, your hands, and face.... feel them releasing, and relaxing.
Once your entire body is relaxed, it will begin to feel heavy. Imagine yourself drifting towards sleep, floating downward like a pearl in a stream. Drift deeper and deeper. Begin counting to ten, slowly. Once you reach ten, you will be in a state of total relaxation and meditation.
When you are done with the relaxation exercise, count backwards from 10 to 1. When you reach one, you will be revitalized and full of energy.

Meditation Exercise
Sit or lay down in a comfortable position, keeping your spine as straight as possible. Close your eyes. Imagine your body getting lighter. Now, imagine that a gentle wave of warmth [or warm water] is washing over your body, beginning with the top of your head. Let the warmth wash over you. Feel the warmth bringing peace to your head as it washes away all tension. Now, allow the warmth to wash down your neck and shoulders. Peace is washing over you and you are relaxed. Let the warmth wash down your arms to your fingertips. Let any tension flow out through your fingertips, disappearing forever. Now, let the warmth wash down your chest and back. Feel the warmth and relaxation wash over your belly and down your thighs. Peace is washing over you and you are relaxed. Let the warmth wash down you knees and calves and then your feet and toes. Let any tension flow out through your toes, disappearing forever. Now, you are relaxed. Let the warmth wash down your entire body again, washing away any left-over tension. You are relaxed. you may remain in this relaxed state for a while, if you like. When you are ready, take some deep breaths and slowly open you eyes.
