Kim,
ah I see, you’re not in contact with a teacher. Had I known that my feedback would thus have been different.
You ask about letting go of the concept of being good at yoga. The desire to let it go is admirable, especially in a culture where holding it, encouraging it, and empowering it is so prevalent. I suspect that retention of intention will serve you. That is to say if it is not pretense, if you want to let go of that, then you likely will.
However this appears to me to be a place where a teacher is most necessary. It is very difficult for us to have a clean view of the self. A sound teacher provides us just that form of honesty and reinforces the concept of transforming ego through the practice and shifting from a practice of doing and accomplishment to one of feeling and experience.
The holding on to competitiveness is what Patanjali calls Abhinivesha - one of the five kleshas or obstacles to our own mindful evolution. Abhinivesha is commonly defined as the fear of death though in this case I’m referring to the fear of death of the Ego. It is only the ego that must perform, be seen, be recognized, be patted on the ishial tuberosities.
In short, we’re all going to die. So what if you never jump through? Who cares? Surely not whatever divinity you align with. Who cares if you sweat bullets? Who cares if you can stand on your thumbs for five minutes? Who cares how lean your muscles are? These things ONLY matter when they impact our lives. If jumping through allows you a deeper relationship with Self, others, and planet then please please remain attached to it and try like the dickens to “get it”. If it does not, then it seems “okay” to let it go.
