Sitkari Pranayama
Sit
erect in a comfortable position. Keep your hands in anjali or gyana mudra for
sometime. Open the mouth slightly, keeping the lips open but teeth together.
Press the tip of the tongue lightly against the lower front teeth and suck the
air slowly through the mouth over the tongue, making a hissing sound. Then
slowly exhale through both the nostrils.
This
pranayama prevents diseases, helps in controlling thirst, hunger and sleep,
improves digestion and purifies the blood stream. Purak is done through the
mouth rather than the nose.
