Cambodian royal ritual life reveals a carefully maintained synthesis in which Brahmanical structures and symbols are enveloped within a Buddhist moral and devotional framework. At court, Brahman priests conduct Vedic-style rites—fire offerings, mantra recitation, consecration of regalia, and astrological calculations—while Buddhist monks chant Pali suttas, confer precepts, and bestow blessings with holy water. Many ceremonies are deliberately ordered so that Brahmans ritually “open” the event with invocations and consecrations, and monks “close” it with merit-making and protective chants. This dual presence reflects the enduring ideals of the king as both devarāja, linked to Hindu deities such as Śiva or Viṣṇu, and dhammarāja, the righteous Buddhist ruler who upholds the Dhamma and supports the Sangha.

The coronation provides a particularly vivid example of this blending. The space is purified with mantras, sacred waters from multiple directions are used in an abhiṣeka-like anointing, and conch shells, incense, and invocations of Hindu deities establish a cosmological legitimacy rooted in Brahmanism. At the same time, Buddhist monks chant Pali texts, the king bows before Buddha images, offers alms, and publicly embraces the Ten Royal Virtues as the ethical horizon of kingship. Royal regalia—crown, sword, discus-like emblems, parasol—draw on Hindu royal iconography and cosmology, yet they are ritually blessed before Buddha images and interpreted as instruments for a lay Buddhist ruler who protects the Dhamma rather than as tokens of a god incarnate.

This same pattern appears in other royal rites that bind the kingdom to the wider cosmos. The Royal Ploughing Ceremony, for example, is led by Brahmans invoking Hindu fertility deities with Vedic mantras and ritual implements, while Buddhist monks bless the fields, chant for timely rain, and frame the event as an occasion for merit-making. The royal ritual calendar relies on Hindu-derived astrology and cosmology—ideas of auspicious hours, directions, and Mount Meru symbolism—yet the lived meaning of these events is expressed through Buddhist practices such as temple visits, offerings, and communal chanting. Palace and ceremonial spaces are laid out according to Hindu cosmic models, but they are animated by Buddhist worship, ordinations, and festivals.

Language and textual traditions further underscore this layered synthesis. Sanskrit and Khmer formulas, inherited from older Brahmanical manuals, coexist with Pali canonical chants, and the interplay of these idioms allows royal ritual to speak simultaneously in the registers of cosmic sovereignty and moral responsibility. Cambodian royal ceremonies thus do not merely juxtapose two religions; they choreograph them so that Brahmanical rites provide the sacral architecture of kingship, while Theravāda Buddhism supplies its ethical content and soteriological aim.
