A few things I have discovered about the Prasaritas: At 0:14' - 0:17' in the video below you can clearly see the moment where, each time, I remember what Richard Freeman says in one of his videos "Turn on the light of the pose". This imagery works well on Prasaritas: it reminds me to engage bandhas and get the abs in, focus the dristi (eye sight point) engage the quads and lengthen the tail bone. Just 7 words make me do all that.
When zoning in on the prasaritas I can clearly feel that my body is just a suit, a coat of sorts, that needs to be stretched to contain the flesh and bones into the shape that the asanas demand. It is one of those poses that completely makes me aware that I am within the confines of a body, and that the body can be re-aligned, re-streched. I don't know why, but this pose just brings out the "workability" of the flesh and bones.
Recently I read a very illuminating post by Grimmly on his own experience on the touchdown of the hands during Prasarita C. I have been working every since I read that on the shoulders and playing with the energy alongside the arms. May not happen soon but I am having some fun trying.
The legs can never get straight enough. At least not for me. I seem to be having a conversation or a dialog with the legs straightening, or not. I feel pain in the back of the legs and so I bend, then I remember to engage the quadriceps and that is when they straighten again. And on and on we dance.
What is your experience with them?
