"Relax your mind, relax your mind,
Makes you feel so good sometimes.
Sometimes, you got to relax your mind."
Even someone who lived as rough a life as Leadbelly, still managed to have some Buddha-nature shine through.
When you relax your mind, it's amazing how many other things follow.
The version I've used here was recorded by the Jim Kweskin Jug Band (it's the only one I have on vinyl) but I found a nice version of Leadbelly performing it here on YouTube.
