Even as one part of the body cares for the other body parts (the stomach digests food for the body, the brain directs the body for the good of the whole, the hands work for the sake of the body, etc.), so each partner in the marriage is to care for the other.
Hata kama vile sehemu moja ya mwili inajali sehemu zinginezya mwili (tumbo husiaga chakula kwa ajili ya mwili, ubongo unaongoza mwili kwa ajili ya mema ya yote, mikono hufanya kazi kwa ajili ya mwili, nk), hivyo kila mshirika katika ndoa ni mhudumu kwa wengine.
