The Law of the Jungle

The Law of the Jungle
(From The Jungle Book)
by Rudyard Kipling

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.
