Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
वीरणस्यात्मजायां तु चक्षुर्मनुमजीजनत् मनुर् वै राजकन्यायां नड्वलायां स चाक्षुषः //
vīraṇasyātmajāyāṃ tu cakṣurmanumajījanat manur vai rājakanyāyāṃ naḍvalāyāṃ sa cākṣuṣaḥ //
From Vīraṇa’s daughter, Cakṣus begot Manu. That Manu—known as Cākṣuṣa—was born from the royal maiden Naḍvalā.
This verse does not describe Pralaya; it preserves Manvantara-era genealogy by naming the parentage and identity of Cākṣuṣa Manu.
Indirectly, it anchors dharma in lineage memory: Purāṇic genealogies legitimize royal succession and the transmission of social duties (rājadharma and gṛhastha-dharma) through recognized ancestral lines.
No Vāstu or ritual procedure is stated here; the verse functions as a genealogical record rather than a temple/ritual instruction.
