Witnessing the space between your thoughts can be an effective means to help you calm your mind and achieve aspects of meditation.
It can be common to hear people ask “How can I clear my head when I meditate?” Often, the more you try, the more that your thoughts seem to arise. This can be entirely expected, as trying to clear your head is also a thought.
So do not try to get rid of your thoughts, as for most people, this will not work. Instead, you need a way to bring focus to the mind, through a process called Ekagrata. Even in a noisy or chaotic mind, there will be spaces between your thoughts. So instead of focusing on the thoughts which you are trying to push aside, apply your focus on the space or gap between the thoughts. All the while, as you continue to focus on the space between the thoughts, witness this space become larger, so that it fills more of your mind. Continue to focus on the space so that it pushes more and more of your thoughts to the side of your mind or your thinking. Gradually this quiet space will grow to provide you with an opportunity to have some calmness of mind, from which you can continue with your other mindfulness or meditation activities.
