व्यासशिष्योत्पत्तिवर्णन (Origins/Enumeration of Vyāsa’s Disciplic Succession) — Chapter on Vedic Transmission Lineages
द्वे सहस्रे शतन्यूने वेदे वाजसनेयके / ऋग्गमः परिसंख्यातो ब्राह्मणं तु चतुर्गुणम्
dve sahasre śatanyūne vede vājasaneyake / ṛggamaḥ parisaṃkhyāto brāhmaṇaṃ tu caturguṇam
In the Vājasaneya Veda, two thousand less a hundred (that is, 1900) ṛg-gamas are reckoned; and the Brāhmaṇa portion is said to be fourfold that.
