Purananuru 188

Even when a man has earned much
of whatever can be earned,
shared it with many,
even when he is master of great estates,

if he does not have
children

who patter on their little feet,
stretch tiny hands,
scatter, touch,
grub with mouths
and grab with fingers,
smear rice and ghee
all over their bodies,
and overcome reason with love,

all his days
have come to nothing.
