African Proverb (Liberia)

American Indian Proverb

Filthy water cannot be washed.
African Proverb (West Africa)

"We call upon the waters that rim the earth,
horizon to horizon,
that flow in our rivers and streams,
that fall upon our gardens and fields,
and we ask that they:
Teach us, and show us the way."

American Indian Blessing (Chinook)

A brook can be a friend in a special way.
It talks to you with splashy gurgles.
It cools your toes and lets you sit
quietly beside it when you don’t feel
like speaking
Joan Walsh Anglund

What makes a river so restful to people
is that it doesn’t have any doubt --
it is sure to get where it is going,
and it doesn’t want to go anywhere else.

Hal Boyle

We cannot make rivers whole unless we wholly understand them.
Rob Brown, Wheeler School, Providence, R. I.

In rivers, the water that you touch
is the last of what has passed
and the first of that which comes,
so with time present.

Leonardo da Vinci
