Agni Purana — Agneya-vidya, Shloka 43
The Description of the Sarvatobhadra Maṇḍala (सर्वतोभद्रमण्डलकथनम्)
एकैकं सप्तधा भूयस्तथैवैकं द्विधा पुनः चतुःषष्ट्युत्तरं सप्तशतान्येकं सहस्रकं
ekaikaṃ saptadhā bhūyastathaivaikaṃ dvidhā punaḥ catuḥṣaṣṭyuttaraṃ saptaśatānyekaṃ sahasrakaṃ
प्रत्येक इकाई को फिर सात गुना किया जाता है; और उसी प्रकार एक इकाई को पुनः दो गुना किया जाता है। इस प्रकार सात सौ चौंसठ प्राप्त होते हैं, और कुल मिलाकर एक सहस्र होता है।
Lord Agni (in instruction to sage Vasiṣṭha)

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.
