Amen! We bring our 5 senses with us to our troubleshooting tasks, and then ignore them to focus on the 6th sense (guesswork!). Use all of them! (Well, maybe not taste...) Take a step back and watch the lights and meters. Listen to the sequence of clicks and buzzes (and the lack of them). Feel the temperature of the chips (the back of your hand is a marvelous thermometer at a few inches above a circuit). All are clues as to what is going on.
This garden universe vibrates complete.
Some may get a sound so sweet.
Vibrations reach on up to become light,
And then thru gamma, out of sight.
Between the eyes and ears there lay,
The sounds of colour and the light of a sigh.
And to hear the sun, what a thing to believe.
But it's all around if we could but perceive.
To know ultra-violet, infra-red and X-rays,
Beauty to find in so many ways.
Two notes of the chord, that's our full scope.
But to reach the chord is our life's hope.
And to name the chord is important to some.
So they give a word, and the word is OM.
