If you learned Parts Integration from Tad James or any other ABNLP Trainer you probably learned to go for maximum impact by eliciting the two parts that are most in conflict with each other.
In many esoteric traditions it is understood that when something is created it’s exact opposite also comes into being. If this thinking is applied to Parts, we see that when a Part is created in the unconscious, its opposite is also created. It’s these two that are integrated by using the pattern and, according to some thinking, resolved to a higher level. The two separate parts cease to exist independently.
However, I also learned this pattern from Ian MacDermott and learned another point of view on this technique. It doesn’t have to be about integrating parts back into the whole, it can be focused on negotiating parts so that they can co-exist. Ian’s demonstrations made it clear that sometimes a part needs to be valued and honoured for its contribution.
Sometimes, rather than automatically seeking to re-integrate a part as quickly as possible, there is value in taking the time to really understand its purpose and validate the aspect of self that it represents.
