Matsya Purana — Bhīma-Dvādaśī
दामोदरायेत्युदरं मेढ्रं पञ्चशराय वै ऊरू सौभाग्यनाथाय जानुनी भूतधारिणे //
dāmodarāyetyudaraṃ meḍhraṃ pañcaśarāya vai ūrū saubhāgyanāthāya jānunī bhūtadhāriṇe //
“(One should assign) the belly to ‘Dāmodara’; the generative organ to ‘Pañcaśara’; the thighs to ‘Saubhāgyanātha’; and the knees to ‘Bhūtadhārin’.”
This verse is not about pralaya; it gives a ritual mapping of divine epithets onto bodily locations (nyāsa), used for sanctifying the worshipper or the deity-image.
It supports the householder’s dharma of daily worship by prescribing a precise internal ritual (nyāsa) that disciplines attention and consecrates the body as fit for pūjā.
Ritually, it is a nyāsa instruction: specific names are installed in specific limbs (belly, organ, thighs, knees), a common step in image-worship and mantra-sādhana described in Purāṇic ritual sections.
