Hi PauliEffect,
The way I look at it is to compare it to a feeling or emotion. Take a woman's perspective, which is probably more easy to understand since women get "stuck" in their emotions more and longer than a man does.
When I feel the effects of an emotion come over me, even though logically I can think thru it or talk myself thru it..."Vicky, you're only feeling this way because you've been focusing on thinking about the things that make you sad and worry", it doesn't have much effect on that emotional state. Once I'm so far into experiencing such an intense emotion, it's not easy to just snap out of it.
But that emotion and that state I'm in at the moment are not my entire self. It's just a passing thing. Eventually it passes and I feel much better, seeing things from a better, higher, happier perspective. The emotion and energy I experienced during that period of time were real things. Just because I cheered myself up and moved on doesn't mean that that moment doesn't exist. More simply stated, it's like looking at one day out of thousands. That one day doesn't represent the total.
So I use that analogy for the "stuck" part of a person who needs retrieval. Of course, reasons for people being stuck can vary greatly, but they don't always have to be because of some awful trauma. I'm sure the intensity of any negative emotion and the energy it exudes can cause the same stuck effect, but maybe just not on such a permanent scale.
It is my belief that we are constantly causing bits of these stuck energy creations, but we are also constantly retrieving them as life goes on, and we don't typically need to do anything about it, as life just seems to take care of things. Like they say, time heals all wounds. I say that love, communication, and growth heals wounds too! And honesty, and other things as well. We just don't usually have to do much to retrieve a lot of these instances because they usually get worked out in one way or another thru our lives. That's what I think.
