Ancient India / Vedic Literature — UPSC Mains Model Answer

The six Vedangas are Shiksha (phonetics), Kalpa (ritual procedure), Vyakarana (grammar), Nirukta (etymology), Chandas (metre), and Jyotisha (astronomy). Each addressed a specific dimension of Vedic study, ensuring the integrity of sacred texts across generations. Together they constitute a comprehensive framework for both linguistic preservation and ritual application.

Nirukta, associated with the scholar Yaska, focused on explaining the etymology and meaning of obscure or difficult Vedic words. This was essential because archaic Vedic Sanskrit had become increasingly unintelligible to later generations. Nirukta thus served as an early form of lexicography and hermeneutics, safeguarding interpretive continuity.

Kalpa dealt with the correct procedure for performing Vedic sacrifices and domestic rites, codified through the Shrauta, Grihya, and Dharma Sutras. It was not concerned with phonetics — that domain belonged to Shiksha. Kalpa's systematic ritual manuals provided administrative-like precision to religious observance.

Jyotisha, the earliest form of Indian astronomy, was primarily utilitarian — determining auspicious lunar and solar timings for sacrificial ceremonies. It reflects how empirical observation of celestial bodies was institutionalised within a religious framework, laying groundwork for later advances in Indian mathematical astronomy.
