In beginning the education of their children and winning them on to progress they follow the "Twelve Chapters". When the children are seven years of age the great treatises of the Five Sciences are gradually communicated to them. The first science is Grammar which teaches and explains words, and classifies their distinctions. The second is that of the skilled professions [concerned with] the principles of the mechanical arts, the dual processes, and astrology. The third is the science of medicine [embracing] exorcising charms, medicine, the use of the stone, the needle, moxa. The fourth is the science of reasoning, by which the orthodox and heterodox are ascertained, and the true and false are thoroughly sought out. The fifth is the science of the Internal which investigates and teaches the five degrees of religious attainments (lit. the “five vehicles”) and the subtle doctrine of karma.
