Breathing is the most natural process, but we do not pay enough attention to it. Start by following your breathing, breath slowly through your nose to your lungs. Imagine how you fill the vital energy. Focus on a small body area, mostly the head, and observe your senses.
Maybe after a while you will feel a slight tingling or warm, which means you are on the right track to start really deeply relaxing and disengaging from the chaos surrounding you. When the tension comes, calm down, people who are worried usually feels warm at the beginning, first obstacle to starting to meditate is the continuous flow of thoughts, the ruins of the past, future plans, anxiety, and others. Don’t blame yourself, because thinking is normal.
To stop the flow of thoughts, imagine that you are an outsider of it, so don’t underestimate them, just capture them. Sooner or later thoughts will start to break. Take a deep breath and exhale a few times, try to focus more on the senses of the body. And be sure to praise yourself for the smallest achievements.
