Anapanasati Sutta is a teaching from the Buddhist tradition that helps us to become aware of our breathing and to use it as a way to bring peace and focus to our minds. It involves focusing on the in breath, and the out breath, and counting each one as it happens. This helps us to stay present in the moment and to observe our thoughts, feelings, and body sensations without getting caught up in them. By practicing Anapanasati regularly, we can become more mindful and peaceful.
