Answer: The dharmas experienced and used are merely the six dusts. Arising due to causes and conditions, they cease due to causes and conditions. Definitely, inside there is no person who can experience, and outside there is no dust that can be used. The Treatise on the Eighteen Kinds of Emptiness says: 'External emptiness is also called emptiness of the experienced. Apart from the six external sense bases, there are no other dharmas that can be experienced. If that which all sentient beings experience and use is merely the six dusts, since inside there is no person who can experience and outside there is no dharma that can be experienced, then both person and dharmas are empty; consciousness-only lacks realms, and is therefore called external emptiness. Because there is no realm, there is also no consciousness, which is internal emptiness, and so forth up to the eighteen kinds of emptiness.'
