The Law of the Wolfpack

"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"

The Jungle Book, by Rudyard Kipling
