The Tipitaka, the Buddhist canon, is replete with references to the factors of enlightenment expounded by the Enlightened One on different occasions under different circumstances. In the Book of the Kindred Sayings, V (SaÃyutta Nikáya, Mahá Vagga) we find a special section under the title Bojjhaóga SaÃyutta wherein the Buddha discourses on the Seven Factors of Enlightenment in diverse ways. In this section we read a series of three discourses or sermons recited by Buddhists since the time of the Buddha as a protection (paritta or pirit) against pain, disease, and adversity.
