Perhaps, but consider: in a sibling comment, codenlearn posted a link to Wim Hof's video, I watched it, and did ten minutes of breathing exercise. He shared some knowledge (open source spirit), it was free (no commercialization), and I would not even remember his username if I hadn't copied it for the sake of this comment (no ego).
I learned more from his comment than I did from yours. You could have shared a better guide, some resource to learn about the original practices, but you didn't. Instead your comment focused exclusively on your offense at the lack of recognition for you(r in-group). What is that if not ego? Group narcissism is still narcissism.
