The yoga we practice is not for ourselves alone, but for the Divine; its aim is to work out the will of the Divine in the world, to effect a spiritual transformation and to bring down a divine nature and a divine life into the mental, vital and physical nature and life of humanity. Its object is not personal Mukti, although Mukti is a necessary condition of the yoga, but the liberation and transformation of the human being. It is not personal Ananda, but the bringing down of the divine Ananda - Christ's kingdom of heaven, our Satyayuga - upon the earth.
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 This veil may completely withdraw or be partially withdrawn.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.
Sri AurobindoMan is a transitional being, he is not final; for in him and high beyond him ascend the radiant degrees which climb to a divine supermanhood. The step from man towards superman is the next approaching achievement in the earth's evolution. There lies our destiny and the liberating key to our aspiring, but troubled and limited human existence — inevitable because it is at once the intention of the inner Spirit and the logic of Nature's process.
