> some of the most meditative and creative of my life

This sounds like a worthy pursuit. We control the most powerful machines to ever have existed, yet it's all too easy to use them for anesthetic distraction. Offline relationship and meditation help develop our capacity to use these machines for something better.

I grew up driving tractors and diggers, it's a very similar thing. Up and down, up and down, Perkins AD3 at 1700rpm for 540rpm PTO shaft speed, it all sounds like a mantra. Write a prayer on a strip of paper, wrap it round the shaft, offer up a prayer nine times a second.
