We are agents of the Creative Spirit in this world. Real advance in the spiritual life, then, means accepting this vocation with all it involves. Not merely turning over he pages of an engineering magazine and enjoying the pictures, but putting on overalls and get on with the job. The real spiritual life must be horizontal as well as vertical; spread more and more as well as aspire more and more.
