If I understood it correctly, the idea was to post a any standing pose, right? This Prasarita Padottanasana C is one of my favorites, because when you start practicing, it feels totally impossible. When the teacher says to bring the hands down to the floor, it just makes you laugh... until one day you have that sensation of your hands touching the floor and you don't quite understand if it's the floor or not.

That is why I love yoga. When you don't think about it, just do the practice, you will amaze yourself. You will notice that anything is possible. That is why it is important to not think. Our minds, especially the subconscious mind, is full of limiting beliefs. These limiting beliefs create a limited life. By the practice of yoga, we can hopefully stop doing that and allow a new level of expansion and flow... I think I will write a post about this, to dive even deeper into this idea of expansion and unlimited life. :)
