One of the ways you can use your Mindfulness practice is to focus on a positive goal that you are wanting to accomplish. How you do this is very important. Visualising an outcome helps reprogram your brain and nervous system to make this happen much easier.
But visualising alone is not enough. You need to be out of your thinking mind and in touch with your body to energise the goal. It takes all parts of your body to be aligned and active to achieve a goal. Especially if it is a new one that you haven’t done before.
If it is new and just out of reach (which is what you want) it can be difficult to visualise it clearly enough and that’s normal. So it requires repetition over and over, correcting and adding more detail each time. That detail should be positive, seeing the end result. It should also feel like you have it now in this present moment. To have that real feeling you need to be in that mindful deep state, in your body.
If you are not in that mindfulness alpha/theta state, then the goal is just a fantasy, a pie in the sky dream that has no legs to stand on. If you don’t take the time to repeatedly feel it throughout your body, nothing is likely to happen.
