The Heavenly Passage Known in the West as Reissner’s Fiber

Abstract

This article explores the hypothesis that Reissner’s fiber, an enigmatic, anomalous, thread-like structure that runs from the center of the brain to the end of the spinal cord, is the neural substrate of suprasensory perceptions of the divine. Justification for this hypothesis derives from a comparative study of descriptions of the “subtle body” from ancient esoteric traditions, testable speculations about altered states of consciousness correlated with the subtle dynamics of the fiber, and the fiber’s evolutionary trajectory in humans from its perinatal involution to its potential regeneration. While adequate testing of the hypothesis will require new technologies, preliminary investigations are underway. The goal of this research is to promote research about Reissner’s fiber with the hope that it could lead to the discovery of a universal religious experience underlying the transcendent unity of religions.
