This essay sets down some of the aims and objectives of the integral Yoga: "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". It also discusses the processes of yoga and the conditions required for sadhana. In 1934 Sri Aurobindo wrote that it represented an early stage of his sadhana and only a part of it was applicable to the Yoga as it had evolved after more than twenty years.
