Ok, here's my counterpoint from the other perspective:
There is a difference between empowering the dark vibes by putting attention on them and going into your shadow to heal and grow.
Attraction is always at work. If one is carrying around unconscious negativity and old pain, one is going to constantly replay versions of their triggers until they deal with them. Thus, dealing with ones shadow by purposefully paying attention to it can be the neccessary component to getting it out of ones field. However, this is VERY DIFFERENT than expressing all the negativity one feels, all the time. As I teach, one must set a container of some kind if one wants to work through heavier vibes, and start and end with love. One of the biggest downfalls of rising spiritual beings is falling into the trap of constant processing, freedom based emotional expression with complete disregard to creating ones reality, that expresses through language like "I have a RIGHT to feel upset, don't tell me to be all Shanti all the time!" Of course you have a right to feel however you feel! But hows that working for you?? Is letting your feelings control what windows are on your screen and what programs are using your RAM a way to have a good life? Is it helping you "feel better" or create what you'd like in your life? Chances are, no. This type of play is very VERY similar to a victim consciousness trap, and it is hard to get out of. One NEEDS to look at the shadows at some point to truly "burn their seeds" as one might translate old sanskrit, but NOT all the time. Inspiration, healthy nervous system and chemistry, laughter, relaxation, these elements are MORE important to health and success and happiness in life than transforming that one samskara (sankara in Pali).
Get some sanga who want to come together, mens circles or womens circles or your intentional community work well, and SET ASIDE A TIME WHEN YOU WILL WITNESS EACH OTHER IN YOUR PAIN AND CHALLENGE AND HEAR EACH OTHERS STORIES, WITH COMPLETE EMPATHY FIRST, AND THEN THE BEST OF REFLECTION. If one engages in a process like this regularly (most people could use a deep dive about twice a week I think) then the system is much lighter the rest of the time, one can live intentionally, and gradually, one transcends shadow.
This is not saying to walk around with a righteous pillar of light up your ass! Your ass muscles just contract to lift the light in your spine ;-) :-P
All jokes aside, it is VERY KIND of you to reflect upon your brothers and sisters awareness if they don't realize they are stressing and making cortisol and adrenaline, ESPECIALLY if they are doing it over nothing, like anxiously waiting for something you can't influence. There is a point where peoples expression becomes so emotionally bogged down that reason won't function, AND IN THAT MOMENT, EMPATHY is DEFINITELY BEST. Don't go telling a tantruming toddler how they are making themselves unhealthy through fitting. And many of us get into pain and upset that is that big, that even if they can understand your "new age" advice to "vibrate on purpose", they need more deeply to be heard to get out of their loop. There is a time and place for emergency processing support. But if the person is aware, it is VERY ADVANTAGEOUS to step back, restore a good vibe, and THEN go into the processing at some point, slowly, carefully, and actually untangle it like combing from the end of dreads to get them out. Diving right in to the thick of the knots is NOT (lol) going to help you get them out. Work inward from the place of peaceful composure deeper and deeper into the shadow. If you DON'T KNOW you have a shadow, and have to have some traumatic experience of freak out or "bad trip" medicine to show you its there, great, now you know, but you don't have to live from the center of it to get out of it, and in fact, you won't, you will stay there building more and more victim neurons that say you are justified in feeling bad and will get to keep on feeling that way for a long time.
May we all find supportive loving environments and people who hold us to living our highest in a peaceful way, and also hold space for us to scream and vomit and explore the depth of our pain, with a loving lifevest and rope to pull us out.
