A saw will become dulled over time and use. At some point one must stop to sharpen it in order to make future cuts easier to make.
To "sharpen the saw" is a centering (or perhaps meditation) technique. Sometimes it is the repetition of an already mostly-mastered skill, but not necessarily acted for some goal but instead acted for the act itself. In this case, it is a form of practice.
