Dharanis function as spiritual formulas, protecting and empowering practitioners. In poetry, they hum beneath the surface—like underground rivers of blessing. Poets describe them inscribed on scrolls, whispered in rituals, or carried in amulets, linking sound to sacred power.

Dharanis are syllabic formulas in Mahayana/Vajrayana Buddhism, believed to protect, heal, or encapsulate sutra essence. Longer than mantras, they often lack literal meaning but carry vibrational power. Used in rituals, amulets, and meditation, they aid memorization and focus. In East Asian temples, dharani pillars inscribe protective spells. Poets rarely quote them directly, but their presence in narrative (e.g., a monk chanting during storm) signals spiritual armor. For students, dharanis illustrate how sound functions as sacred technology in Buddhist cultures.
