Mindfulness has nothing to do with the spiritual or religion. It is merely paying attention to this moment, right now. You do not have to believe anything, you just have to learn to and practice focusing your attention in the here and now. Anxiety is always about the future and we cannot know the future. Some of my anxiety I deal with using my imagination, imagining a good future outcome instead of imagining a bad one. If my husband is late coming home from a business trip, it is because he has stopped to buy me a present, not because his plane crashed But if I am very anxious or upset and having trouble thinking, etc., then I focus on what is around me right now. One can only focus on one thing at a time so I keep my focus on what I am doing right that moment, get out of my head and use my 5 senses instead. You just control your mind and its jabbering by using your body/senses: Mindfulness Made Simple | Psychology Today
