All dharmas are the nature of tathāgatagarbha

All dharmas are the emptiness (śūnyatā) of the tathāgatagarbha; in essence they are the tathāgatagarbha nature, and there are no dharmas as such. Yet the illusory phenomena of all dharmas still exist and can be perceived, and they also have illusory functions. For example, the five aggregates (pañcaskandha) and the physical body are illusory, empty, and false, but the illusory functions of the physical body still exist, so we can see one another. Time and space are the same: they are illusory, empty, and false, yet they have their illusory functions and can be perceived. Because of time, material form has different sequences of before and after, and material form can also exist and be stored within space.
