Kammavaca (Book of Rules) is the Pali term for a ritual text consisting of a set of passages extrapolated from the Theravada Buddhist canon, the Tripitaka (Triple Basket), that relate to ordination, bestowing of robes, election of senior monks, designating sacred ground and days for fasting and meditation, dedication of monasteries, release from monastic vows, and other rules of Buddhist monastic life. These highly ornate manuscripts are generally commissioned by lay members of society as a work of merit, to be presented to monasteries when a son enters the Buddhist order as a novice or is ordained as a monk. Although these regulations were strictly observed in other Theravada Buddhist countries, only in Burma were the manuscripts of the Kammavaca given such preeminence and so lavishly adorned.
