Every contemplative tradition recognizes powerful inner dimensions we can access through focused practice. We often hear about the Yoga of Inner Light (phosphenes, visual radiance) and the Yoga of Inner Sound (subtle, spontaneous tones). But there is a third, forgotten pathway, the most fundamental and physical of all: The Yoga of the Inner Body. This … Continue reading The Inner Pulse of Consciousness: Rediscovering the Yoga of the Inner Body

Phosphenes & the Ouroboros: How the Brain’s Inner Light Turns Self-Reference into Sacred Vision
Why our inner “visual grammar” and the loop of self-reference make the sense of the sacred both repeatable and deeply personal, and how studying those loops can bridge neuroscience, religion and art.

Importantly, he stressed that these types are not sequential stages (like a ladder of progression) but rather modes of experience that often overlap. In most mescaline states, one type tends to dominate, while … Continue reading The Vision Taxonomy of Dr. Rouhier, in his classic work on mescaline intoxication
When Sound Becomes Light: Synaesthesia, Mescaline, and the Phosphene Connection
Among the many mysteries of human perception, synaesthesia is quite interesting. Crossing of the senses where sound becomes colour, where touch radiates as light, or where vision itself resonates like a musical chord. In early mescaline research, such synaesthetic states were already frequently documented. Investigators noticed that the excitation of one sensory organ would spill … Continue reading When Sound Becomes Light: Synaesthesia, Mescaline, and the Phosphene Connection

A New Taxonomy of Klüver Form Constants based on new subjective reports of phosphenes induced by transcranial stimulation
We discuss first the results of this study: "Kvašňák, E., Orendáčová, M., & Vránová, J. (2022). Phosphene Attributes Depend on Frequency and Intensity of Retinal tACS. Physiological research, 71(4), 561–571. https://doi.org/10.33549/physiolres.934887" The study is extremely valuable to define the form constants which can be percieved with closed eyes, as internal light phenomena. We will then generate a … Continue reading A New Taxonomy of Klüver Form Constants based on new subjective reports of phosphenes induced by transcranial stimulation

Here's what is known or inferred about this concept: 1. Qi Transformation in Daoist Inner … Continue reading On the refinement of internal energy into light

The beauty of this work lies not in its metaphors, but in its attempt to capture what illumination feels like, and to hint that such states are not only real but may have subtle but measurable correlates in the body-mind … Continue reading Inner Light, Alpha Blocking, and the Careful Use of Scientific Metaphors in Spiritual Practice
