Matsya Purana — The Ravi-Śayana
साम्नामधीशाय करद्वयं च संपूजनीयं द्विज रेवतीषु नखानि पूज्यानि तथाश्विनीषु नमो ऽस्तु सप्ताश्वधुरंधराय //
sāmnāmadhīśāya karadvayaṃ ca saṃpūjanīyaṃ dvija revatīṣu nakhāni pūjyāni tathāśvinīṣu namo 'stu saptāśvadhuraṃdharāya //
Obeisance to the bearer of the chariot drawn by seven horses. O twice-born one, in the nakṣatra Revatī the pair of hands should be specially worshipped for the Lord who presides over the Sāmans; likewise, in the Aśvinīs, the nails should be worshipped.
This verse is not about pralaya; it teaches a ritual mapping of nakṣatras to specific limbs/features of the deity (especially the Sun), indicating a liturgical and iconographic focus rather than cosmological dissolution.
It supports the householder’s (and ruler’s) dharma of maintaining daily/seasonal worship: observing auspicious timings (nakṣatras) and performing limb-specific veneration as a disciplined devotional practice aligned with Purāṇic ritual order.
Ritually, it prescribes nakṣatra-based worship of specific parts—hands in Revatī and nails in Aśvinī—within a broader pratima/arcana framework; such prescriptions inform how an image is contemplated and honored in temple-pūjā sequences.
