Concept: Knowledge can be compressed into algorithmic rules (saṅkhyā-sūtra) for reliable reproduction—here applied to chandas enumeration.
Application: Use the stated multiplication/doubling steps as a quick mental algorithm when deriving metrical totals or checking enumerations in prosody lessons.

FAQs
It gives a technical rule of numerical multiplication and doubling used for metrical/prosodic enumeration (chandas), arriving at the count 764 and relating it to a total of 1000.
Beyond theology and ritual, the Agni Purana preserves technical śāstra material—here, chandas/prosody and numerical computation—showing its scope across linguistic sciences and systematic enumeration.
Mastery of chandas supports correct recitation and preservation of sacred texts; accurate metrical knowledge is traditionally linked with purity of mantra-prayoga and the merit of faultless chanting.
