"Poison" is an apt metaphor!
Here's an interesting aspect: what possessed the dude who told Lisa she was fat? Is there any agenda by the purveyor of the poison? Was there any reality in which he was the pawn of something else, which intends to dispirit (something of which he was unaware, that is)?
The guy that said the nasty words is rather uninteresting for this lesson. As you will see (or of course already know) such nasty things can come from anyone and it is an energy that has followed man for eons. Some times it is friends or mates that deliver these nasty things, but most often people get hurt by relatives, parents or other close persons.
The origin of this kind of poison is: Lies.
It was a lie that Lisa was fat (and indirectly that meant: unattractive and not smart).
Now we know that most people can handle such statement, and that we have seen worse things.
As you may have noticed, I have recently written a chapter in a government report about rape against children. It is very common, more than 50 percent of the cases, that those who make the violence toward the child are known by the child, either as a parent or as a close relative.
We also found out that, severe psychological problems, misuse of drugs and alcohol and also suicide in adult age is more common for victims of these crimes that happened during childhood. Please keep in mind that is not only girls that get offended, young boys are also a group that suffers from sexual offences. And also the perpetrators have in some studies been noted to have a more than 100 times increased risk for suicide. A great part of the offenders is not feeling very well either.
The damage that children get after sexual offences and molestation is comparable to the poison paradigm, but in most cases that kind of offence has a more complicated structure in energy terms, because other areas than the traditional areas of thorn and poison, are infected or damaged as well.
