The practice of yoga 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 into the life of humanity. It is not personal ananda, but the bringing down of the divine ananda, the Satya Yuga, upon the Earth.
— Sri Aurobindo, (1872-1950), Indian philosopher and reformer
