Matsya Purana — Rasakalyāṇinī Vrata: Magha-based Goddess Worship
रम्भायै वामकुक्षिं च विशोकायै नमः कटिम् हृदयं मन्मथाधिष्ण्यै पाटलायै तथोदरम् //
rambhāyai vāmakukṣiṃ ca viśokāyai namaḥ kaṭim hṛdayaṃ manmathādhiṣṇyai pāṭalāyai tathodaram //
Salutations to Rambhā—who presides over the left flank; salutations to Viśokā—who presides over the waist. (Salutations) to Manmathādhiṣṇyā—who presides over the heart; and to Pāṭalā—likewise, who presides over the abdomen.
This verse does not describe Pralaya; it is a ritual-iconographic instruction assigning specific divine names to bodily regions as part of nyāsa (sacralizing the body or the deity-image).
Indirectly, it supports the householder’s duty of proper worship (pūjā-vidhi): performing nyāsa and salutations with correct deity-name placement is presented as a disciplined, dharmic way to conduct daily or temple ritual.
Ritually, it is anganyāsa: invoking/placing deity-aspects onto specific limbs (left flank, waist, heart, abdomen). Such mappings are used in consecration and worship of images in Puranic temple practice and in mantra-nyasa before pūjā.
