A previously undocumented 10th-century manuscript titled 'Pratyaksha-Jyoti' has been unveiled from a private collection in Tirupati. The work focuses on the philosophy of 'Luminous Perception,' positing that the eyes do not simply receive light but emit a cognitive beam that illuminates the essence of the object. This 'active vision' theory contrasts sharply with the passive models of perception found in other contemporary schools.
The text is attributed to a lost lineage of Kashmiri scholars who settled in the south, and it contains detailed descriptions of 'Antar-Drishti' (internal sight) as a method for validating logical inferences. By integrating optics with epistemology, the manuscript provides a fascinating glimpse into the interdisciplinary nature of ancient Vedic research.
