We can only do what we attempt and believe we can do.
How do we free space in our heads and hearts for new thoughts and beliefs?
Begin by walking calmly and paying attention to your thoughts and emotions. Start Inhaling on one step and exhaling on the next. As you are relaxed in this state and need not invest attention to maintaining it, add a step to both phases (inhale, exhale) and repeat until you reach your current limit of X steps per inhale and the same for exhale. Once there, Go down one step and then up again and then, add two steps at the same time and press the number of steps upwards until all you can do is breath and walk.
This will clear your head from outside thoughts and allow the heart to reset and release emotion that was held inside and not moving anywhere.
The simplicity of this work is deceiving and this is just the first stage.
Much more is hidden in plain sight.
