I would say that as a grownup a person pull in some situations because of their actions, yes. But to say everyone pulled everything in that happened to them i think is to mindcontrol people. You better watch out what youre thinking if this is really how it is!! and when you start to try to control your own thinking, then it gets pretty hard to live.
I can tell you that i was told so many times that i have to be careful what i postulate, to the degree i was scared to think. And of course i got thoughts i wished i never had and so on. When im not in scientology, this is not a problem anymore. I dont care what i think, because its just thoughts. and the thoughts are much more often just good, now that i dont need to have that pressure on me.
To look at things a certain way and then act on it is a different thing for me, of course if you are a positive and strong person that thinks that things will go well, then they are more likely to go well.
But i think its crazy to consider for example that a child that is abused pulled it in somehow. But i met a lot of scientologists that do think so.
I know how they think, that to see how you can be cause makes you more able to solve things, but there is a point were a person is just completely heartbroken, and then i also think some compassion will fit, not a seccheck.
