Why do terrible things happen after a revelation?

A simple example of this is let’s say you talk about love and forgiveness and being positive. By the end of the day you’re fighting over stupid little things that didn’t matter before and everyone is being super negative. It’s like a snap back, but why? It seems like the most painful kind of lesson. Makes me feel like just giving up and breaking everything that meant something. Anyway I didn’t. I’m just frustrated. Dealing with one spiteful thought after another. It’s like a tsunami of negativity. See I’m being negative now. What has to be done is make a concious effort to think of something positive. Then some whiny voice in my head says what about this sour feeling? It’s like I just want to sit in the rain and get wet.

More to the point, is there some need for us to be negative that starves when we learn some positive thing? Or do we doubt what we hear? Maybe we all have that “devil on our shoulder” saying that’s just a bunch of crap easier said than done?

Well I plan to get to the bottom of this. I must find a resolution to this and future times of this most confusing of lessons.
