In the ordinary use of the word "pure" we find the same meaning: for instance, when we speak of pure water or pure milk, we mean that the original substance is unmixed with any foreign element. Therefore a pure life is the term used to express the effort of man to keep his spiritual being untainted by the false values of the worldly life. It is the constant search for the original self, the desire to reach it, and the means employed to recover it, which alone can truly be called purity of life; but the. term can be applied with the same meaning to any part of man's life.
