[813] Therein, as to the phrase "trainings are recited concerning whatever ties there are in the world" (tattha sikkhānugīyanti yāni loke gadhitāni): "Trainings" (sikkhā) means elephant lore, horse lore, chariot lore, archery, ophthalmology (treatment with the probe, sālākiya), surgery (sallakattiya), medicine for the body, spirit-medicine (bhūtiya), and the treatment of children (komāratikicchā). "Are recited" (gīyanti): they are recited, told, spoken, explained, expressed. Or else, "are recited": they are learned, mastered, retained, borne in mind, and discerned for the obtaining of the ties. "Ties" (gadhitā) is a designation for the five kinds of sensual pleasure (kāmaguṇa): forms cognizable by the eye that are wished for, desirable, agreeable, pleasing, connected with sensuality, provocative of lust. For what reason are the five kinds of sensual pleasure called "ties"? For the most part, devas and human beings desire the five kinds of sensual pleasure, take pleasure in them, long for them, and hanker after them; for that reason the five kinds of sensual pleasure are called "ties." "In the world": in the world of man (manussaloka). Hence, "therein, trainings are recited concerning whatever ties there are in the world."
