Physical education for the body to be effective must be rigorous and detailed, far sighted and methodological. This will be translated into habits. These habits should be controlled and disciplined, while remaining flexible enough to adapt themselves to circumstances and to the needs of growth and development of the being.
Sri AurobindoThe 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.
