The navel region is the centre of the vital. It is from here that the movements of the vital rise upward. Above the navel and behind the chest is the centre of the play of emotions and below this takes place the play of the physical. Mulฤdhฤra is the base of the physical. In between the Mulฤdhฤra and the navel, there is another centre of the vital.
Sri AurobindoMaterial things are not to be despised-without them there can be no manifestation in the material world.
Sri AurobindoThreefold are those supreme births of this divine force that is in the world, they are true, they are desirable; he moves there wide-overt within the Infinite and shines pure, luminous and fulfilling.... Of that which is in mortal in mortals, and possessed of the truth, is a God and established inwardly as an energy working out in our divine powers.... Become high uplifted, O Strength, pierce all veils, manifest in as the things of the Godhead.
Sri AurobindoThere is a veil between the Supermind above and the lower Prakriti below - the veil of ingrained formations. This veil may completely withdraw or be partially withdrawn. Thus even if there is some little opening, with the contact of Light from above the lower nature will get slowly changed.
