Today in Thailand wearing of an amulet (phra khrueang), a small image of Buddha or of a famous monk usually enclosed in some form of casing and attached to a cord or chain worn around neck, is among most widespread of religious practices.1) The principal benefit of such amulets is protection from dangers of various kinds, verging into a more positive desire for good fortune. In Khun Chang Khun Phaen (KCKP), a massive folk epic dating back to late Ayutthaya era, demand for protection against dangers is a dominant theme, and many devices are used for this purpose.In study of religion, power, and social ordering in Thai society, key concepts have been merit and power, prowess, patron-client ties, kingship, and so on.2) All these concepts betray a top-down view, a focus on explaining why certain people are powerful. The concept of protection comes into play when angle of vision switches to bottomup and concentrates on what people seek from religion, power, and social institutions. In historical study, nature of few sources available (chronicles, laws) has favored top-down view. However, literary sources that emerged from a popular tradition offer possibility of moving outside this straitjacket. Similarly, in contemporary study, concept of protection or security has emerged with increasing attention to analysis of popular religious practice. In his recent pathbreaking work, Justin McDaniel argues that besides well-known Buddhist qualities of non-attachment, compassion, and enlightenment, everyday practice points to the importance of security and protection (khwam plotphai, kan pongkan), abundance . . . , graciousness . . . , and heritage (McDaniel 2011, 219).In this article, we trace concept of protection from late Ayutthaya era to present. The early sections analyze meaning and prominence of protection in KCKP, and range of devices and practices deployed in its pursuit. The later sections trace emergence of modern amulet and changing role of Buddha in business of protection.Khun Chang Khun Phaen as a SourceKCKP is a long folk epic that developed in an oral tradition of storytelling for local audiences. The plot, set in provincial urban society of central Siam, is a love triangle ending in tragedy. Khun Phaen is handsome and dashing but his family was ruined after his father was executed by king for an error on royal service. Khun Chang is richest man in local town but fat, ugly, and crass. The two compete for lovely Wanthong. Khun Phaen woos and weds her, but Khun Chang then uses his wealth and court connections to take her away. The rivalry continues through two pitched battles, two court cases, trial by ordeal, jail, treachery, abduction, and other mayhem. Tiring of this disorder, king summons three and commands that Wanthong be executed for failing to choose between two men.Probably tale originated around 1600 and developed in an oral tradition of storytelling for local audiences, becoming hugely popular by eighteenth century, and very long (21,000 lines excluding late sequels). It was then adopted by court, converted to written form, extended with new episodes and sequels, and embellished with fancier poetry. The first printed edition appeared in 1872, but work is known today through an edition published in 1916-17 by Prince Damrong Rajanubhab, half-brother of King Chulalongkorn.3)Works like KCKP that develop through repeated interaction between performers and audiences over a long period, as did many of classics of world literature, come to reflect tastes and values of their society. While court revisions greatly changed surface of KCKP, plot, tone, structure, and rhythm of work retained much of their original character. The epic is a rare document that reflects society and mindset of premodern Siam.Protection in Khun Chang Khun PhaenThroughout tale, characters seek protection (khum-khrong, pong-kan) against risks, dangers, and threats (siang, phai, antarai, khuk-kham) in order to ward off sorrowful hardship (thuk) and achieve peaceful contentment (suk). …
