下明同事中，略辯其相，不遍歷九門分別。測云：准上類釋應有九門，以其同事用前諸行共眾生同，更無別法，准上可知，故略不論耳。所以知有九門者，如下文說：從一切施乃至同事乃至清淨施乃至清淨同事，故知皆有九門。

Below, in explaining "sharing common tasks," its characteristics are briefly analyzed without distinguishing them by traversing all nine gates. Ce says: "Following the analogy above, there should be nine gates. Because sharing common tasks uses the previous practices together with sentient beings and has no distinct dharma apart from them, it can be understood following what precedes, and hence it is simply not discussed at length. How is it known that there are nine gates? As the subsequent text states: 'from all generosity up to sharing common tasks, and from pure generosity up to purely sharing common tasks'—therefore, we know that all have nine gates."
