The emptiness of the essence of form is itself the emptinesses of the essences of the aggregates such as feeling. Similarly, the emptiness of the essence of the eye-source is itself the emptinesses  of the essences of all twelve sources. Likewise, the emptiness of the essence of the eye-constituent is itself the emptinesses of the essences of all eighteen constituents. Equally so are [the emptinesses of the essences of] the infinite categories of things due to the distinct divisions in things, locations, times, and contexts. For whatever is the emptiness of the essence of one thing is itself the emptinesses of the essences of all things. In spite of the fact that jars and bowls for example are distinct, space is not distinct. While things such as form are distinct, insofar as they all lack the essential arising of form, and so on, they are not distinct. By understanding the lack of the essential arising of merely one phenomenon, one understands the lack of the essential arising of every phenomenon.
