Matsya Purana — The Cave-Sanctuary: Jewel-Lake
समाकुञ्चितजानुस्थमणिबन्धेन शोभितम् किंचिदाकुञ्चितं चैव नाभिदेशकरस्थितम् //
samākuñcitajānusthamaṇibandhena śobhitam kiṃcidākuñcitaṃ caiva nābhideśakarasthitam //
Adorned by a bracelet (maṇibandha) near the evenly bent knee, and with the arm slightly flexed, the hand is to be placed at the region of the navel.
This verse does not address pralaya; it focuses on pratima-lakṣaṇa—precise sculptural posture and ornament placement for a deity image.
Indirectly, it supports dharma through correct temple patronage: a king or householder who commissions images should ensure the icon follows śāstric posture rules, preserving ritual efficacy and tradition.
It gives a technical iconographic prescription: the wrist/bracelet position, a slight bend of the arm, and the hand placed at the navel region—details essential for correct deity installation and worship.
