Let's make it simple. The world around us is made of photons and we are made of DNA.
When scientists put photons in a vacuum (a vessel with the air removed), the photons randomly distributed themselves in the vacuum and then human DNA was added into the vacuum and guess what? In a short time the photons started to get together and replicate the exact DNA geometry (shape). The photons became DNA.
So you, by simply existing, can shape the world around you, but you miss a link on how to do it. The DNA that was inserted in the vacuum with the photons wasn't afraid, didn't had anxiety, had no hate, no stress, but we go through all these negative states every day (most of us deal with this). The DNA was CALM and PRESENT and that's why the world (photons) started shortly to align with the DNA.
BE CALM AND PRESENT AND YOUR WORLD WILL SHIFT!
