Love
Although almost noone can agree on a single definition of love, most agree that it plays a significant role on their psychological well-being (Te Taha Hinengaro) and our Te Whare Tapa Whā. Love is not an emotion nor a feeling, but a chemical reaction driven by extreme feelings of respect, euphoric attraction and willingness to put another's happiness and well-being above your own. Love and lust have very similar characteristics, but unlike lust, love is long lasting.
Other definitions are mostlikely emotionally charged and bear no logical or rational reasoning. They have no correlation to the bigger picture; that is: love for family members or even pets, but are purely directed at one's partner. However with your partner love can in some cases give you a lust-like feeling after years of being in a close relationship. Love is so nebulous to many, even the famous band 'Foreigner' wrote a song titled "I want to know what love is".
