The "Vaisheshika Sutras" manuscript has survived into the modern era in multiple versions and the discovery of newer manuscripts in different parts of India by Thakur in 1957 and Jambuvijayaji in 1961, followed by critical edition studies, suggest that the text attributed to Kanada was systematized and finalized sometime between 200 BCE and the start of the common era, with the possibility that its key doctrines may be much older.
