"And this is the law of the jungle;
As old and true as the sky.
And the wolf that shall keep it will prosper;
But he wolf that shall break it must die.
As the creeper that girdles the tree trunk,
The law runneth forward and back.
For the strength of the pack is the wolf,
And the strength of the wolf is the pack."
– Rudyard Kipling, The Law of the Jungle (from The Jungle Book)
