The six Vedāṅgas — the limbs of the Veda
षड्वेदाङ्ग
Also written: vedanga · six vedangas · limbs of veda · shiksha kalpa vyakarana nirukta chandas jyotisha
A Veda that cannot be pronounced correctly, performed correctly, parsed, etymologised, scanned or timed is unusable. The six Vedāṅgas are the sciences that make it usable — and each of them grew into a full discipline in its own right.
| Vedāṅga | Called | Science | Function |
|---|---|---|---|
| Śikṣā | The nose | Phonetics and phonology | Exact pronunciation, accent, quantity and articulation of every syllable |
| Kalpa | The hands | Ritual procedure | How every rite is performed — Śrauta, Gṛhya, Dharma and Śulba Sūtras |
| Vyākaraṇa | The mouth | Grammar | The structure of the language — culminating in Pāṇini's Aṣṭādhyāyī |
| Nirukta | The ears | Etymology and semantics | What the words mean, especially the difficult ones — Yāska's Nirukta |
| Chandas | The feet | Metre | The metres in which the mantras stand: gāyatrī, triṣṭubh, jagatī and the rest |
| Jyotiṣa | The eyes | Astronomy and time-reckoning | When a rite must be performed — the calendar, the seasons, the sky |
Śikṣā
The science of sound: place of articulation, effort, pitch, duration. Preserved Vedic accent for millennia.
Kalpa
Ritual procedure — and inside it the Śulba Sūtras, the oldest geometry in the world.
Vyākaraṇa
Pāṇini's 3,959 rules: the first complete generative grammar of any language.
Nirukta
Yāska's etymology — the oldest surviving work of semantics.
Chandas
Metre, and with Piṅgala the binary notation and the sequence later called Fibonacci.
Jyotiṣa
The eye of the Veda — time, calendar, and the position of the sky at every moment.
In this section
Śikṣā — the science of sound
Vedic phonetics: articulation, accent, duration and the discipline that preserved the Veda's sound unchanged for thousands of years.
Kalpa — ritual procedure, and the world's oldest geometry
The Śrauta, Gṛhya, Dharma and Śulba Sūtras: how every public rite, household rite and legal duty is performed — and the altar geometry that produced the Pythagorean theorem in India.
Vyākaraṇa — grammar, and Pāṇini
The Aṣṭādhyāyī: 3,959 rules that generate the whole of Sanskrit, the first formal generative system in human history, and why computer science rediscovered it.
Nirukta — etymology and meaning
Yāska's Nirukta, the oldest surviving work on word-meaning, its method, and the debate on whether Vedic words have fixed or derived sense.
Chandas — metre, and the first binary notation
The Vedic metres, Piṅgala's Chandaḥśāstra, and the mathematics it produced: binary numbers, the sequence later called Fibonacci, and Pascal's triangle.
Jyotiṣa — the eye of the Veda
The science of light and time: its three skandhas, the nakṣatra system, the pañcāṅga, and why a rite's moment matters as much as its procedure.
