විසුද්ධිමග්ග is a Theravada Buddhistcommentary written by බුද්ධගෝෂ හිමි approximately in 430 CE in Sri Lanka. It is considered the most important Theravada text outside of the Tipitaka canon of scriptures. The Visuddhimagga's structure is based on the Ratha-vinita Sutta ("Relay Chariots Discourse," MN 24), which describes the progression from the purity of discipline to the nibbana, considering seven steps.
↑See, for instance, Upatissa et al. (1995), p. xliii: "The Visuddhimagga is a household word in all Theravāda lands. No scholar of Buddhism whether of Theravāda or of Mahāyāna is unacquainted with it."
↑See Thanissaro (1999) for a translation of the Ratha-vinita Sutta. See the various Visuddhimagga printings listed below to see the manner in which this sutta is explicitly integrated into the work.
