Using advanced multispectral imaging and deep-learning algorithms, scholars have deciphered a series of rare 4th-century BCE inscriptions found in the Aravalli Range. Titled the 'Vak-Prana-Anuvada', these stone carvings detail a highly technical metalinguistic theory that explores the ontological relationship between the spoken word (Vak) and the vital breath (Prana).
This discovery provides empirical evidence for the early systematic study of phonetics as a spiritual discipline. The inscriptions outline how the resonance of specific syllables was believed to harmonize the practitioner's internal biological rhythms with cosmic cycles, predating later Tantric and Yoga-Sutra commentaries by several centuries. The find is being hailed as a major breakthrough in the history of linguistic philosophy.
