26.113

「如是十智至為所緣故」者，此即第三明十智相緣。《婆沙》一百七云「法智緣下、類智緣上，故不相緣。如有二人同住一處，一人觀地、一人觀空，如是不相見面。」餘文可知。

"As for these ten knowledges […] taking as their object of cognition": This is the third section, explaining the ten knowledges mutually cognizing one another. The Mahāvibhāṣā, fascicle 107, states: "Dharma-knowledge cognizes what is lower, and subsequent knowledge cognizes what is higher, so they do not cognize each other. It is like two people dwelling in the same place, one observing the earth and the other observing the sky; thus they do not see each other's faces." The rest of the text is readily understandable.
