It might help to have someone read this to you slowly so you can practice:
Grab and object--a stone, coffee cup, pen. Sit with you feet flat on the floor. Close your eyes. Take a slow, deep breath and feel the air move through your nose, down your throat, into your lungs and back up and through your mouth and past your lips. Feel you chest expand as you breath, how it displaces your body as it moves. Feel your forehead relax, feel your cheeks relax, feel you mouth relax, your neck muscles relax, your shoulders relax, your arms, your hands, feel your chest relax, you hips relax, your legs, your feet relax. Feel your feet where they touch the floor. Feel them exchange the energy with the earth. Feel the object in your hand. Run your fingers along its edges. Feel its smoothness, its sharpness, its imperfections. Notice any changes in its texture. Breath deep, feel your breath and when you are ready, open your eyes.
