It looks like you have found the right article on how to practice the Breathing Meditation. Than rejecting this, instead try to concentrate on training the mind. All the Buddha’s teachings— on generosity, virtue, and meditation, or on virtue, concentration, and discernment—are aimed at training the mind because the mind is what shapes our experience of pleasure and pain, happiness and suffering. A well‐trained mind can deal with issues that you come across in meditation. This require effort. They go against the grain. You have to learn not to let your resistance to the effort get in the way. You need a clear sense of cause and effect. That’s what discernment is all about: seeing what really works in terms of cause and effect, what doesn’t really work, and then adjusting your actions accordingly. We’re here to train the mind to be its own best friend.
One way of doing this is to focus on your breath. It is best if you’ll sense the breath as the feeling of the air moving in and out of the nose, but if it is difficult, then be aware (but not solely focus on) the rise and fall of the abdomen, the rise and fall of the chest. Sometimes can sense even in your arms or your legs whether you’re breathing in or breathing out. Allow breath to come in as long as is comfortable, and then allow yourself to breathe out as long as is comfortable. Try to sensitize yourself to what feels good right now in terms of the breathing. Think of yourself as hovering around the breath. You’re not squeezing it out; you’re not forcing it in; you’re just staying very close to it, watching it, letting it adjust in whatever way feels good, giving it space to adjust. The more satisfying the breath is, the easier you will find it to stay with the breathing. If the mind wanders off, just bring it right back to the breath. If it wanders off again, bring it back again.
Mind will want to wander around. That’s what the mind is used to doing. But if you’re firm with it, and if you can master just this one skill, you change the way you relate to your body, you change the way you relate to the present moment, you have a greater reserve of wellbeing to draw on in any situation. Do not be too grim about the meditation. Find pleasure in, and be happy even if it a short while that you were with the breath. It takes time, it takes training, it takes discipline. But you must remain happy to do it well.
