Elder Michael Thrasher once told me that the eagle feather has two sides. If the feather had only one side then Eagle could not fly. On one side we find mind/intellect, body/movement and spirit/emotion. Once these are balanced a person is balanced. On the other side there is institution/education (and not just Western style education), process (the movement on one's path) and ceremony. Once these are balanced then a person's life is balanced. When the two sides of the feather are balanced then we have proper behaviour.

Funny thing is.......Eagle doesn't care if its feathers have two sides....It just opens its wings and flies up to Creator.
