It looks like you have confused causation with correlation.
You write in your article using the word "mindful", "As we expected, mindful people reported feeling less distress due to the exclusion incident". There is no such sub-species of human as this, only people who may or may not engage in cognitive exercises that are labelled as such. Brain imaging provides inferential evidence, but it does not distinguish between types of people in this context.
You are overselling what mindfulness is.
