The more I teach the more I realize the importance of finding where each person's body can balance the best.
The body is divided into front and back AND left and right. The midline, or central axis runs down our body, it is commonly thought of as the spine. I believe that in our yoga practice we can feel the midline all the way from our arches to the crown of our heads. Or - we want to be able to feel it so that we can move from it!
The midline will change depending on what we are doing. If we are able to find and hug the midline in various yoga asanas we will find stability, strength, and ultimately balance.
I love the visualization of a rolling pin rolling you down from a seated position to a lying position. Give it a try at home and feel the deep core engagement as well as the spinal articulation.
Now - try to use these same principles but turned around - in ubhya padangusthasana and other poses at the end of primary.
