The fruit of the quickening and abiding action of a higher principle at the centre of the being, operating so as to suffuse the whole of it, pervade the whole of it, to its utmost limits, which, seating itself in the heart of the thoughts and affections, works and weaves itself into all the life tissues and becomes part and parcel of the very flesh and blood. No idea, however true, however elevated or elevating one may feel it, is spiritual till it centralises in the heart and affects all the issues thereof.
