A meditation cushion's function is to support your body in achieving proper alignment during meditation. Those who sit on the floor for long periods may feel tension in their backs, hips, or legs, making their practice less enjoyable. A meditation cushion provides a solution by elevating the hips above the knees, allowing for a more relaxed and stable seated position. This reduces physical discomfort and directs more attention to the senses.
A cushion is not just comfort in itself; it is a preparation for a special kind of foundation from which one meditates into gyana. It focuses one's attention on the breath, mantras, or other forms of visualization and not on the body.
