The Vedic Samhitas were difficult to understand, and much learning was required to comprehend them. Before approaching the Samhitas, the Vedangas were to be studied. The Vedangas were a group of texts on six topics, shiksha or phonetics; vyakarana or grammar; chhandas or metre; nirukta or etymology, alternatively glossary; jyotisha or astronomy and astrology; and kalpa or ritual.
Most of these various Vedanga texts were written in sutras, a sutra being a short statement providing information in a compressed way. These sutras too, could only be understood by a learned person.
Did this ensure that only the elite could ever understand the Vedas?
