Jayapataka Swami:  One way you can avoid having people eat from your plate, don’t leave any remnants! Eat everything! Or when they are serving out don’t accept more than you can eat! If you do then you are asking for it for people to take your remnants. Eating remnants means they give you their karma and take your good qualities. So if you have any bhakti as good quality, then they may share that. If they have any sins, they give you, free! You are very merciful! The guru is supposed to give remnants, but the other devotees, they eat all their prasadam.
