The “Linked Discourses on the Faculties” contains 178 discourses on various sets of “faculties” (indriya). The “five faculties” of faith, energy, mindfulness, immersion, and wisdom are the most natural fit in this context. However the chapter also finds room for discourses on a wider range of 22 faculties, including the six sense faculties, five affective faculties (kinds of feeling), three faculties relating the process of enlightenment, and three concerning biology and gender. This flexible category thus serves as a link between the teachings on wisdom and those on the path.
