Jathara parivartanasana A improves digestion and blood flow, helps with migraine and headaches, and stimulates the vagus nerves.
When used in a spiritual practice, this twist applies pressure to the solar plexus area and massages the abdominal organs, stimulating the manipura (navel) chakra -- the chakra that governs self-esteem, willpower, ego and self-discipline. This asana also activates the muladhara (root) chakra, which governs one's sense of groundedness and stability. Additionally, jathara parivatanasana A increases all five elements in the body and reduces both the vata and pitta doshas.
Jathara parivartanasana A can be practiced with a blanket folded under the knees for extra support, or with a hand pressing the knees down for a deeper stretch.
