Sound and Metre — Śikṣā & Chandas
before this →The Source — Śruti
The Veda is not read; it is recited. If the sound drifts, the mantra is void. So the first two instruments are the ones that keep the sound from drifting.
The six limbs
sound
śikṣā — phonetics — how a syllable must be made
metre
chandas — prosody — the measured shape of a line
word
vyākaraṇa — grammar — how words combine
meaning
nirukta — etymology — what a word unpacks to
time
jyotiṣa — astronomy — when the rite falls due
action
kalpa — procedure — how the rite is performed
Sound is the carrier
Śikṣā
A prātiśākhya records, for each school, exactly how its Veda is to be sounded: place of articulation, effort, duration, pitch. The svara — the pitch accent — is not ornament; it is part of the text. Change it and you change the meaning.
the keyOral fidelity here is an engineering achievement, not nostalgia.
A text preserved across millennia with zero scribal variants is what śikṣā bought.
VARṆAthe syllable, exactly made
SVARAthe pitch, exactly placed
PADAthe word, unbroken
Metre as memory
Chandas measures the line. The metres are counted in syllables — gāyatrī (24), uṣṇih (28), anuṣṭubh (32), bṛhatī (36), paṅkti (40), triṣṭubh (44), jagatī (48) — and the count is what lets a reciter know an error has occurred before anyone else does. The metre is a checksum.
