瑜伽論記 24.28

24.28

In the prose, it first explains establishment. As for there being four dharmas that can nourish the sense faculties and primary elements, and [give] bodily strength: solid nutriment can serve as nutriment for bodily strength. Second, as for joy and pleasure: the mental factor of contact associated with joy and pleasure serves as nutriment for joy and pleasure, not taking contact associated with grief and suffering. Third, single-minded yearning toward agreeable matters: this is the tainted mental volition, which can serve as nutriment for yearning toward all agreeable objects. The fourth serves as the basis of the preceding three nutriments. The phrase "three gates" refers precisely to the preceding three nutriments.
