...It is good to strive for purity, but if you conceive of purity as a fight against the filth and dust of the world, you doom yourself to obsession and futility. The only way to achieve actual purity is to realize your essential oneness with all things. If you are one with everything, then even filth is pure. For this to happen, you must transcend all distinctions in yourself, resolve all contradictions. With this erasure, the mirror-bright soul and the dust are all dissolved in a single purity.
