In ekāsan (eating in a formal Jain arrangement), the principle is to avoid waste and show reverence for food. If you move the patla (plate) during eating, try to finish what you have started and not leave a large portion uneaten. If you must stop or the plate is moved for a valid reason, aim to complete or share the remaining food rather than discard it carelessly. The core idea is ahimsa and not wasting food, so minimize leftovers and respect the meal.
