Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
सारस्वतं पदं याति पुनरावृत्तिदुर्लभम् एतत्सारस्वतं नाम रूपविद्याप्रदायकम् //
sārasvataṃ padaṃ yāti punarāvṛttidurlabham etatsārasvataṃ nāma rūpavidyāpradāyakam //
He attains the Sārasvata state—the station of Sarasvatī—from which return is rare. This attainment is called “Sārasvata,” and it bestows knowledge of forms (rūpa-vidyā).
It does not describe Pralaya directly; it emphasizes a higher spiritual/intellectual attainment (“Sarasvata pada”) that is difficult to fall back from, implying stability beyond ordinary cycles of return.
It frames learning—especially disciplined sacred knowledge—as a royal/householder duty: cultivating Sarasvatī’s domain (wisdom, right learning) leads to elevated status and steadiness, supporting righteous governance and ordered living.
By stating that “Sarasvata” bestows rūpa-vidyā, the verse points to the authoritative knowledge needed for correct forms—useful for pratima-lakṣaṇa (iconographic proportions) and, by extension, Puranic temple-image standards.
