Purity is a process through which the life rhythm of the spirit manifests. It has worked for ages through the mineral, the vegetable, the animal, and the human kingdoms, passing through and arriving with all its experience of the way at that realization where the spirit finds itself pure in essence, in its pure and original condition. The whole process of creation and of spiritual unfoldment shows that the spirit, which is life and which in life represents the divine, has wrapped itself in numberless folds, and in that way has, so to speak, descended from heaven to earth. And the next process is to unwrap itself, and that unwrapping may be called the process towards purity.
