काचित्पृष्ठकृतादित्या केशनिस्तोयकारिणी शिलातलगता भर्त्रा दृष्टा कामार्तचक्षुषा //
kācitpṛṣṭhakṛtādityā keśanistoyakāriṇī śilātalagatā bhartrā dṛṣṭā kāmārtacakṣuṣā //
A certain woman, with the sun at her back, stood upon a stone slab letting water drip from her loosened hair; her husband beheld her then with eyes troubled by desire.
This verse is not about pralaya or cosmology; it is a narrative snapshot focused on human emotion (kāma) and perception.
By portraying the husband’s desire-aroused gaze, the verse supports the Purāṇic ethical theme that householders should recognize sense-impulses and practice restraint and right conduct rather than being driven by passion.
No Vāstu or temple-rule is taught directly; the only physical detail is a ‘stone slab/surface’ (śilā-tala), used as scene-setting rather than architectural prescription.
