Purity is the process through which the life-rhythm manifests; the rhythm of that indwelling spirit which has worked through the ages in mineral and plant, in animal and man. For its effort, through all these experiences, is to arrive at that realization where it finds itself pure, pure in essence and pure from all that could affect its original condition. The entire process of creation and of spiritual unfoldment shows that the spirit which is life itself, and which represents the divine in life, has wrapped itself in numberless folds, and in that way has, so to speak, descended from heaven to earth.
