For sitting meditation you should sit in a straight dignified position, with your head, neck and hips in line. If seated in a chair, have your feet flat on the ground and if seated on the ground, place a meditation cushion or firm pillow under the sit bones to elevate the hips above the knees.
Sitting meditation allows you to maintain your focus more easily than laying down, while still allowing you to free your mind from processing information. Using your breath as an anchor, you create awareness of the present moment and connect with any feelings or sensations you may be experiencing. Meditation can help reduce stress and improve your overall emotional and mental health.
