i also have only been doing yoga for 6 weeks but i will be doing a TTC course in 3 months time. Initially i was concerned about my ability to teach after that, if lets say, for example, i can’t do some of the asanas myself , then how could i teach? Well, my teacher said that my own practice and my teaching are two entirely separate things and being a good teacher is primarily about knowing what yoga is. (which he said alot of yoga teachers dont know).
It is not about me performing my own asanas infront of the class, but rather how i actually teach.I could have been doing yoga for ten years , but if i dont explain well,or have other qualitites of a good teacher, patience etc or if my ego is out of control then my teaching will be poor. It is not hypocritical to teach headstand when one hasnt mastered it oneself for example. If you have a commitment to your own practice and are working as best you can towards improving that then its fine.
one of my favourite yoga teachers sometimes shows us asanas that she cant do herself, as she started the practice late at age 40, so there are physical limitations but as she explains so beautifully and has a wonderful nature and excellent manner it doesnt matter at all.
