Support equals release. We use propping in the poses which along with other elements, actually elicits the reliable release of muscle and the opening into poses. When a yoga practice is done like this, there is true alignment in every asana.
Bones are for support. We learn to lean on our bones and use them for the support they are meant to provide.
A tight muscle is a weak muscle and a weak muscle is a tight muscle. We learn that every tight muscle is a weak muscle. These weak, tight muscles constrict blood flow (along with the proper nutrition and oxygen) as well as diminishing the flushing of toxins.
Perhaps the most important thing we learn is how to experience our inherent bliss. When Swami took Svaroopa's name from the yoga sutras. she reflected on this teaching, “tada drashtuh sva-rupé vasthananm." This means the moment the mind becomes quiet “the seer sees himself in his own true nature.” In other words, the moment the mind becomes quiet, we can then experience the inherent bliss of our own inner self.
So the core opening releases tight muscles and, even more interestingly, tight minds. The core opening also leads to a true core strengthening. By unraveling deep internal tightness, tissues replenish, joints align, breathing and digestion improve, all organs, nerves and glands are nourished, and the relaxation response kicks in. Svaroopa yoga inspires a cascade of openings that detoxify and restore the body. Along with these physical openings comes a feeling of pervading peace, a diving inward, a coming home.
