"There are five ways in which a son should minister to his mother and father as the eastern direction. He should think: ' Having been supported by them, I will support them. I will perform their duties for them. I will keep up the family tradition. I will be worthy of my heritage. After my parents' deaths I will distribute gifts on their behalf.'"

-- Digha Nikaya: Sigalaka Sutta: III

"One who is always helpful and kind, Who guards her husband as a mother a son, Who carefully protects the wealth he earns -- Such a wife is called a mother...One who rejoices at her husband's sight, As one friend might welcome another, Well raised, virtuous, devoted -- Such a wife is called a friend"

--Anguttara Nikaya 7:59
