In the beginning of all things, wisdom and knowledge were with the animals, for Tirawa, the One Above, did not speak directly to man. He sent certain animals to tell men that he showed himself through the beast, and that from them, and from the stars and the sun and moon should man learn.. all things tell of Tirawa.
All things in the world are two. In our minds we are two, good and evil. With our eyes we see two things, things that are fair and things that are ugly.... We have the right hand that strikes and makes for evil, and we have the left hand full of kindness, near the heart. One foot may lead us to an evil way, the other foot may lead us to a good. So are all things two, all two.
