There are countless meditation techniques available. You don’t have to try them all. You just have to find one that works for you and deepen your practice with that one. Just like when you are looking for a sport when you want to increase your physical fitness. Development over how well you can control your mind is most likely to happen when you stay with one meditation and become experienced with one technique. You also don’t weekly change the sport you do. Meditation isn’t looking for entertainment for the mind, it is training it.
The meditation you find here helps you to focus your attention on the moment, there where every meditation technique wants to bring you to. The constant wandering of the attention to thoughts about what happened in the past or scenarios for the future, makes the mind restless. Mindfully being present in the moment, just observing everything that manifests in our awareness and just letting it be, leads to calmness and stability.
