"Now this is the Law of the Jungle -- as old and as true as the sky;
And the Wolf that shall keep it may prosper,
but the 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."
From ‘The Law of the Jungle’ by Rudyard Kipling
