Good are friends when need arises;
good is contentment with just what one has;
good is merit when life is at an end,
and good is the abandoning of all suffering.

Dhammapada 331

The friend who is a helpmate,
the friend in happiness and woe,
the friend who gives good counsel,
the friend who sympathises too --
these four as friends the wise behold
and cherish them devotedly
as does a mother her own child.

Digha Nikaya 31
