उच्चीय स्वयम् उद्ग्रथ्य कान्तेन कृतशेखरा कृतकृत्यमिवात्मानं मेने मन्मथवर्धिनी //
uccīya svayam udgrathya kāntena kṛtaśekharā kṛtakṛtyamivātmānaṃ mene manmathavardhinī //
Raising her hair and braiding it with her own hands, and with her beloved arranging the crest-ornament upon her head, the woman—who heightened the power of Kāmadeva—deemed herself as though her purpose had been fulfilled.
This verse does not discuss pralaya or cosmology; it is a śṛṅgāra (romantic) description focused on personal adornment and the intensification of desire (Manmatha).
Indirectly, it reflects the householder sphere—mutual intimacy and adornment within companionship—showing the Purāṇic acceptance of kāma when situated in human life, though no explicit rājadharma or gṛhastha-dharma injunction is stated here.
No vastu, temple-architecture, or ritual procedure is mentioned; the technical focus is poetic imagery of hair-braiding and a head-ornament (śekhara) as markers of beautification.
