What are you meaning when you say “dealing with”? For me, when I talk about “dealing with” negative things (I don’t label things as “positive” or “negative;” those are unhelpful labels for me), I’m meaning shift your relationship with that thing so that it’s less “negative.” That process of shifting leads to the “accepting” you were talking about a few posts up.
I’m going to quibble with your premise that you “manifest through awareness.” That’s not been my experience. If we did “manifest through awareness,” we wouldn’t have a whole slew of manifestors worrying about and trying to clean up their subconscious (AKA unaware) limiting beliefs and whatnot.
I believe that we “manifest through active vibration,” of which we may or mayn’t be aware. Frankly, I’m not a big fan of that phrase. It’s a little too airy-fairy for me, but it’s the best phrase I’ve come upon so far which captures the dynamics I see at work.
A person might go through life with an active vibration (a story, a belief, a decision about who they are or how people treat them, etc) and react to life through the lens of that vibration, manifesting (in both real and “spiritual” senses) more that matches and fulfills that active vibration.
You’re wise to ask this because, as you can see by your question, “suppressing” doesn’t allow for any shifting. It’s almost the opposite of the conditions conducive to the shift and integration that was being recommended. Suppressing IS counterproductive, not the other way around.
I know it seems counterproductive to you. I’m willing to bet that the reason it seems counterproductive to you hinges on the difference between what you’re meaning when you say “observe” and what those who are recommending that observation are meaning. When you truly “just simply observe” in the recommended sense, you’re no longer labeling that event or energy as “negative.” It simply is. That event or energy becomes something that you once experienced, with about as much charge as a unwanted fashion choice you used to make when you were 5 years old or your old habit of biting your nails. Just “something that you once did” or “something that once happened to you.” IOW, through that practice (so that you are truly able to “just simply observe”) you’re shifting your perspective–from “this thing is negative and must be suppressed or otherwise banished” to integration, wholeness, and oneness. That’s how you transcend.
Most people don’t “just simply observe,” not at first. Instead, they usually replay their recordings that they have in their head, which are as edited and skewed as reality TV. (And those recordings once served a useful purpose.) It takes some practice to truly “just simply observe” in the way that idea is usually taught.
And that’s not the only way of releasing, integrating or transcending something negative. As you will recall, I described to you a method that was more active and participatory than “just simply observing.” And there are tons more methods. All the effective methods that I know are based on the opposite of “suppressing” and require varying degrees of “awareness.”
