# Vi Nature

"Vim is not permanent. Nvi is not permanent. Vi itself is not permanent,
only vi-nature. Emacs has vi-nature, nano has vi-nature, even Notepad 
has vi-nature. You narrow your sights, you grow attached, and hence 
you do not grasp the true value of your poem’s subject."

 - Master Wq, Vim Koans
