27.94

引利樂果故者，教誡示導以能如實方便說法，故能令他引當利益果（人天果也）及安樂果（涅槃果也），前二示導無此勝能，由是故教誡最為尊勝也。

Regarding "and brings about the fruit of benefit and happiness": because the demonstration of admonition can expound the Dharma with skillful means as it truly is, it can cause others to bring about the future fruit of benefit (the fruits of humans and devas) and the fruit of peace and happiness (the fruit of nirvāṇa). The first two demonstrations do not have this superior capacity, and for this reason admonition is the most eminent.
