Araimandi is a very important posture in Bharatanatyam. It becomes a comfortable posture with practice. In this posture, the back should not jut out, the stomach should not protrude and the torso should not bend forward. The 'Brahmasutra' (the vertical imaginary line passing through the centre of the body) is in balance. This means that the araimandi (half sit posture) adjusts according to the height of the dancer.
