It's likely that you've come across a version of the Prayer Of The Woods sign in your travels, and no matter how many times you see it, it's a pretty darn nice thing to read before walking off into the trees:
I am the heat of your hearth on the cold winter nights, the friendly shade screening you from the summer sun, and my fruits are refreshing draughts quenching your thirst as you journey on. I am the beam that holds your house, the board of your table, the bed on which you lie, and the timber that builds your boat. I am the handle of your hoe, the door of your homestead, the wood of your cradle, and the shell of your coffin. I am the bread of kindness and the flower of beauty. 'Ye who pass by, listen to my prayer: Harm me not.
