Abstract

In Thailand the pre-reform Therav?da meditation system, bor?n kamma??h?na, is now practised only by small and isolated groups. To promote detailed comparative study of bor?n kamma??h?na, the tradition of it taught at Wat Ratchasittharam, Thonburi, is explored through a translation of a text on?n?p?nasati attributed to Suk Kaitheun, the head of its lineage. This is followed by a detailed discussion and comparison with the description of the same technique in the Visuddhimagga. Some close connections between these two sources are identified and it is speculated that, despite features concerning nimitta, bodily location, terminology etc. that are diagnostically distinctive for bor?n kamma??h?na, its method for?n?p?nasati can be seen as a rational development of earlier techniques advocated by Buddhaghosa.
