Summary
Mystics across cultures, from Teresa of Ávila to Tibetan sage Milarepa, have reported seeing intense inner light during deep meditation. New analysis reveals these visions match patterns of phosphenes—natural light phenomena in our visual system. By comparing Teresa's detailed accounts with those of Hildegard of Bingen and Longchenpa, researchers found that mystical luminosity experiences follow consistent stages during contemplation and altered states of consciousness, suggesting a universal basis for spiritual light visions.
Abstract
This paper examines the visionary experiences of Saint Teresa of Ávila (1515–1582) as described in The Life of Teresa of Jesus, through the lens of contemporary phenomenology and the six-phase taxonomy of meditation-induced phosphenes. Special attention is given to Chapters 27–38, including her iconic vision of pure inner light and the Transverberation experience. We argue that Teresa’s imaginative and intellectual visions display a striking resemblance to structured forms of endogenous light perception, particularly in the advanced phases of phosphene progression. To contextualise these findings, we compare her descriptions with those of Hildegard of Bingen (1098–1179) and Tibetan yogis such as Milarepa (c. 1052–c. 1135) and Longchenpa (1308–1364), revealing a cross-cultural phenomenological consistency. This analysis supports the hypothesis that experiences of mystical luminosity represent a shared neurophenomenological substrate underlying diverse contemplative traditions across time and culture.
