The stability of the gas-field system in the Galaxy is examined to show that it is difficult to maintain a stable configuration due to numerous energy releasing phenomenon occurring in the Galaxy. However, it is argued that, as in the case of our atmosphere, hydrostatic equilibrium is expected in the Galaxy on a global scale. A summary of the advances made in the study of the global equilibrium is presented. The major postulates and predictions from some of these studies are compared with the observations. The usefulness of detailed observation of nearby edge-on galaxies in radio and X-ray regime is brought out.
