Sutra in English : Vedang = Limbs of Vedas
Swami Dayanand Saraswati Commentary : The scriptures of ‘SikSha’ = education, ‘Kalpa’, ‘VyaakaraNa’ = Grammar, ‘Nirukta’ = Etomology, ‘Chhanda’ = Prosody, and ‘Jyotisha’ = Astronomy, written by Vedic Seers, are called ‘Vedang = Limbs of Vedas’.
Comment in English : Note — The Vedanga ( = limbs of the Veda) are six auxiliary disciplines that had been developed in ancient times and connected with the study of the Vedas.
1. Shiksha — phonetics, phonology, pronunciation. This auxiliary discipline has focused on the letters of the Sanskrit alphabet, accent, quantity, stress, melody, and rules of euphonic combination of words.
2. Chhandas — Prosody. This auxiliary discipline has focused on the poetic meters, including those based on a fixed number of syllables per verse, and those based on a fixed number of morae per verse.
3. Vyakarana — Grammar and linguistic analysis. This auxiliary discipline has focused on the rules of grammar and linguistic analysis to establish the exact form of words and sentences to properly express ideas.
4. Nirukta — Etymology, explanation of words, particularly those that are archaic and have ancient uses with unclear meanings. This auxiliary discipline has focused on linguistic analysis to help establish the proper meaning of the words, given the context they are used in.
5. Kalpa — Ritual instructions. This field focused on standardizing procedures for Vedic rituals, rites of passage rituals associated with major life events such as birth, wedding, and death in the family, as well as discussing the personal conduct and proper duties of an individual in different stages of his life.
A Kalpa is the combination of four scriptures, namely — ‘Grahya-Sutra’, ‘Shrotra-Sutra’, ‘Shulba-Sutra’, and ‘Dharma-Sutra’.
6. Jyotisha — Right time for rituals with the help of the position of constellations, and astronomy. This auxiliary discipline focused on timekeeping.
