This study examines the lived spiritual communication experiences of nine adherents of the Budi Daya belief system in Cibedug Hamlet, Lembang, West Bandung, Indonesia. Employing Moustakas’s (1994) Transcendental Phenomenology — selected for its capacity to systematically uncover essential experiential structures through epoche, phenomenological reduction, and imaginative variation — the study investigates what spiritual communication experiences Budi Daya adherents undergo and how these shape their vertical (human-divine) and horizontal (human-human/nature) communicative relationships. Data were collected from nine purposively selected informants through in-depth interviews, participant observation during community rituals, and documentary review. Three invariant themes emerge from the cross-case analysis: (1) cognitive-reflective experience manifested as inner spiritual struggle and intrapersonal dialogue (textural description: Indra, Ecep, Euis Shelian); (2) ritual-behavioral experience expressed through the symbolic and collective dimensions of the Mipit Amit ceremony; and (3) social-communal experience realized through solidarity, togetherness, and interreligious harmony. The study’s novelty lies in its proposal of a dual-channel spiritual communication framework — bridging transcendental and cultural communication theory — grounded in the indigenous lived experience of a non-mainstream local belief community in Indonesia, advancing existing spiritual communication scholarship by demonstrating that transcendental and cultural communication are mutually constitutive in indigenous religious practice.
