Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
भुजं भुजाग्रं माधव्यै कमलायै मुखस्मिते भूललाटं च रुद्राण्यै शंकरायै तथालकान् //
bhujaṃ bhujāgraṃ mādhavyai kamalāyai mukhasmite bhūlalāṭaṃ ca rudrāṇyai śaṃkarāyai tathālakān //
He assigns the arm and forearm to Mādhavī; the gentle smile upon the face to Kamalā; the brows and forehead to Rudrāṇī; and likewise the locks of hair to Śaṅkara.
This verse is not about Pralaya; it focuses on iconographic/ritual symbolism by assigning specific bodily features to specific deities, a common Purāṇic method for sacralizing the divine form.
Indirectly, it guides householders and patrons (including kings) in correct devotional practice—supporting proper worship and consecration by understanding which features are ritually associated with which deities.
Ritually, it reflects a nyāsa-like mapping used in consecration and worship of images; architecturally, it supports Pratima-Lakṣaṇa standards by linking sculptural features (face-smile, forehead, hair) with specific divine identities.
