I discussed this with a friend(who has some EFT background) yesterday and here is another thought on this
This is a great idea because it at least stops the actor from becoming a road-block in corrective actions. But a critic can argue that if one disconnects from their deed they might feel less responsible about fixing what was broken. So the approach could be constructed as an excuse(as all great ideas have been historically).
So we need to give a complete picture of this idea by mentioning the other qualities that we may be taking for granted but others wont. It would be somewhat like this(sorry if that sounds like an algorithm :))
(Consider circle inside circle, 1 being innermost )
1) Always look for opportunity to make things better.
2) Learn from observing wrong actions and do not repeat them.
3) Disconnect from your deed.
The idea here is that if I grow outwards and if one of my actions are found to be wanting quality 1) will make me look for an opportunity to make things better. Most of the time I might be the best person to fix what I broke. Quality 2 will make me not repeat it. Also the cool part is that I am not fixing the broken thing out of guilt/shame but out of habit.
Also I would like to stress something that Sri Eknath mentioned in one of his books. We need to practise disconnect not only with action that are found wanting but also with actions that are praiseworthy. Often I find myself using this approach more in the negative situation(to calm myself) and letting myself forget about this in situation where I am praised. We can never reach the finish line if we practise this only 50% of the time.
