everything is possible.
For whom emptiness is not possible,
nothing is possible.
Emptiness is not nothingness. On the contrary, it is the infinite potential for everything to appear. For example, because a cup is empty (meaning, it is not a solid block of matter), it is possible to pour liquids into it. If it were not empty, there would be no space in which liquids could be poured or contained. Therefore, emptiness is the necessary condition for all phenomena to manifest.
Furthermore, whether a cup temporarily contains liquids or not, its own nature is to be empty: its characteristic emptiness does not change —it is precisely its emptiness that makes it a suitable container. In the same way, the nature of the phenomenal world is emptiness. Because it is empty, everything can appear.
