5.88

As for its meaning: fine dust motes are called "dust", and greed and the like are also called "dust", because both share the meaning of defilement. The trichiliocosm is called a "realm", and the cause of defilement is also called a "realm", because both share the meaning of being a cause. It can also be that the trichiliocosm is the realm of the vessel (the physical world), whereas defilements constitute the realm of sentient beings. Here it singles out and excludes the dust of greed and the like, as well as the realm of defiled causes; it refers only to the dust of the earth and the trichiliocosm realm. This concludes the explanation of the above meaning, entirely as previously stated.
