Sri Aurobindo has brought and implanted upon earth a new aspiration, the aspiration for terrestrial perfection, for an integral fulfillment of life. Savitri serves as an intermediary to awaken and help this aspiration to grow in man.
There is no harm in the vital taking part in the joy of the rest of the being; it is the participation of the vital that makes it dynamic and communicates it to the external nature.
