After we eat our food, there is a blessing that we say, called boreh nefashot. It goes like this: “Blessed are You… who creates numerous souls and their deficiencies; for all that You have created with which to maintain the life of every being. Why would we be thanking God for creating a deficiency? The deficiencies in our life give space for others to help us. If we were all self-sufficient, there would be no need for kindness or human interaction at all.
