Swara Yoga — the “Science of Breath” documented in the Shiva Swarodaya — teaches that the dominant nostril at any moment reveals whether the Ida (lunar / parasympathetic), Pingala (solar / sympathetic) or rare Sushumna (central) nadi is active. Aligning your activity with the flowing swara can dramatically improve focus, digestion, sleep and creative output.
Sit upright, exhale, then compare left and right nostril airflow. Select the one that feels clearly more open.
