An authoritative study of the indigenous religion still practiced in Guatemala based on extensive original research and participant observation. Jean Molesky-Poz draws on in-depth dialogues with Maya Ajq'ijab' (keepers of the ritual calendar), her own participant observation, and inter-disciplinary resources to offer a comprehensive, innovative, and well-grounded understanding of contemporary Maya spirituality and its theological underpinnings. She reveals significant continuities between contemporary and ancient Maya worldviews and spiritual practices. Molesky-Poz opens with a discussion of how the public emergence of Maya spirituality is situated within the religious political history of the Guatemalan highlands, particularly the pan-Maya movement. She investigates Maya cosmovision and its foundational principles, as expressed by Ajq'ijab'. At the heart of this work, Ajq'ijab' interpret their obligation, lives, and spiritual work. Molesky-Poz then explores aspects of Maya spirituality, including sacred geography, sacred time, and ritual practice. She confirms contemporary Maya spirituality as a faith tradition with elaborate historical roots that has significance for individual, collective, and historical lives, reaffirming its own public space and legal right to be practiced.
