Studies  report that meditation can relieve anxiety in the brain. This is because meditation has a calming effect on the brain. Since worry is rooted in anxiety, getting your nerves under control can help you worry less or not at all. This relaxes your body. When you are able to relax your body, your mind takes that as a sign that you are not in danger and it can start the process of relaxation.  If you can't cross your legs, sit in any way that is comfortable for you. You can lie down, but be sure not to get too comfortable or you may fall asleep. If you sit in a chair, be sure there is a soft area around you in case you do fall asleep during meditation. This can happen to some people because of the intense relaxation they experience. You have an inner calming mechanism - your breath. When you focus on breathing, you will notice if you are breathing too quickly. If you are, just slow it down by breathing in deeper and exhaling completely. Try counting down your breaths. Breathe in for three seconds and then breathe out for another three seconds. Hold your breath for just a second or two before you exhale. Keep it all slow and steady to relax. Pay attention to what is going on inside of you while you are meditating. If you feel anxious, repeat the word “calm.” You may pick a different word or even a sound, as long as it is something that calms you. If you think of something that worries you, don't fight it off or you'll just get anxious. Consider it for a moment and then let it go. You may even want to say, "Let it go..." To bring yourself back to your day, open your eyes slowly, sit quietly for a moment, and then get on your feet. Stretch if you need to and walk away feeling relaxed and totally at peace. Easing yourself into your day will keep you from getting anxious, which can lead you to start worrying again.

How would you rephrase that briefly using Vietnamese?
Bắt đầu thiền mỗi ngày ngay lập tức. Ngồi khoanh chân và đặt hai cánh tay bên người. Nhắm mắt và tập trung vào nhịp hít thở. Tập trung vào cảm giác của bản thân trong khoảnh khắc này và cho phép bản thân cảm nhận sự bình yên. Chầm chậm đứng dậy.
