The Buddha on love for parents and family

Support for one's parents,
assistance to one's wife and children,
consistency in one's work:
This is the highest protection.
— Sn 2.4

Mother & father,
compassionate to their family,
are called
Brahma,
first teachers,
those worthy of gifts
from their children.
So the wise should pay them
homage,
honor
with food & drink
clothing & bedding
anointing & bathing
& washing their feet.
Performing these services to their parents, the wise
are praised right here
and after death
rejoice in heaven.
— Iti 106
