Hi Spiral,
In general , I see the different exercises as different opportunities to self heal, regenerate and transform. They do have there differences in form, experience and focus. Sometimes the focus is more towards body, sometimes breathing, sometimes losing a sense of self as a body and merging more with the whole of the universe. Different catalysts to promote self healing and transformation in different ways, or stimulate different positives in transforming self. Your sense of body,breath,universe,light, mind, spirit, soul,,,,,all somewhat different, in how they surface in experience coming from the different exerice alignments and focus's.
love,
