Meditation is supposed to develop awareness, help focus your attention, and relax while increasing your focus. At one of my current clients we are developing a Software as a Service (SaaS) application. We have developed the following "meditative principles":

1. It's not done until the tests are done.
2. If it's broke, fix it first.
3. If it's not in a script or code, it doesn't exist.
4. Don't explain, do it (but ask questions if you don't understand).

And finally (with apologies to Bobby McFerrin),

 "Don't worry, be agile".

Here is a little song I wrote
You might want to sing it note for note
Don't worry be agile
In every software we have some trouble
When you worry you make it double
Don't worry, be agile

Ain't got no place to lay your head
Somebody came and took your machine
Don't worry, be agile
The manager say your code is late
He may have to litigate
Don't worry, be agile
Look at me I refactor
Don't worry, be agile
Here I give you my url
When you worry call me
I make you agile
Don't worry, be agile
Ain't got no time ain't got no style
Ain't got not money to make you smile
But don't worry self organize
Cause when you worry
Your face will frown
And that will bring everybody down
So don't worry, be agile (now)

There is this little song I wrote
I hope you learn it note for note
Like good little developers
Don't worry, be agile
Listen to what I say
In your software expect some trouble
But when you worry
You make it double
Don't worry, be agile
Don't worry don't do it, be agile
Put a smile on your face
Don't bring everybody down like this
Don't worry, it will soon pass
Whatever it is
Don't worry, be agile
