Start with doing yoga as a moving meditation. Yin Yoga or Yoga Nidra might be a very soft introduction to bring your mind & body into a meditative state. Lie down at the end, take your time and start appreciating Shavasana.
Start feeling every body part at once by simply putting all your mental energy & thoughts into a specific area of your body. Start with your feet, move on to your knees, your stomach, chest, arms, fingers. End with your head. Start to feel thoughts as clouds passing by. After some tries you find your mind empty, released & at ease.
Every time is different. Some times it will feel very easy, on some days you won’t feel it working at all - But still you stopped 5 minutes from doing whatsoever, switched off your brain for a bit. It will help you feel calm on the long run 💎
