Caraka who was the first man to refine the treatise of Agnivesa thoroughly and enlarge it with his interpretations and annotations. His contributions in this respect were so spectacular that the original treatise in its new form began to be known on the name of Caraka himself instead of the original author. The original Agnivesa-tantra in bried (Sutra) style was enlarged with his annotations (Bhasya) by Caraka. Thus Caraka was the Bhasyakara of Agniveda’s work as was identified as Patanjali, the author of Yogasutra and Mahabhasya.
