A jogger runs at her pace. Suddenly someone overtakes her. The jogger notices how it gets more difficult to run, how every step feels more heavy, because the other one runs so much quicker whereas she already struggles. Then she tells herself: "Well, it does not matter that the other one runs faster than me, I run at my pace and there is no need to win a race. My goal is different and it is ok to be overtaken."
What happened? The jogger feels a sensation and starts to find rational reason why this sensation should not be there. Instead, she could behave differently. She could allow the sensation to be there and let it grow even bigger in order to be able to observe it very closely.
Thus, instead of talking herself into how she should feel she could sense how she does feel. Well, what could possibly show up if she did? First of all she notices how heavy it feels to run and how this casts her down. Maybe some thoughts come up like "others are better than me, others are faster than me, I am bad, I am of no value …"
This could continue and very deep emotional injuries might show up and the jogger might remember hurting childhood experiences which still have an impact. A very old pain might suddenly be triggered simply by being overtaken while running.
As long as we rationally suppress our sensations such triggers do hit us. By consciously being aware of our sensations and allowing them to be we are then able to get to the root cause of our issues and therefore release them.
Suddenly the hundred things which used to bother us are not relevant any longer because the root problem is detected and solved. Quite often the conscious awareness of our sensations is sufficient to release deep issues.
