An international team of researchers in Tajikistan has unearthed a 4th-century Gandharan birch bark scroll that details the 'Tejas-Vada', or the Metaphysics of Radiance. This rare find, written in Kharosthi script, presents a unique ontological system where light is considered the primary substance of the universe, preceding both matter and mind. The text bridges the gap between early Upanishadic thought and the later development of light-based metaphysics found in certain Tantric traditions.
The discovery was made within a Silk Road waystation, suggesting that these sophisticated philosophical ideas were part of a vibrant intellectual exchange across Central Asia. Preliminary analysis reveals complex arguments regarding the 'internal illumination' of consciousness, which scholars say predates similar concepts found in Neoplatonism by several decades.
