Matsya Purana — The Nakṣatra-Puruṣa Vrata: Worship of Viṣṇu’s Cosmic Body through the Lunar M...
नक्षत्रपुरुषं नाम व्रतं नारायणात्मकम् पादादि कुर्याद्विधिवद् विष्णुनामानुकीर्तनम् //
nakṣatrapuruṣaṃ nāma vrataṃ nārāyaṇātmakam pādādi kuryādvidhivad viṣṇunāmānukīrtanam //
One should undertake the vow called “Nakṣatra-Puruṣa,” which is of the very nature of Nārāyaṇa; and, beginning with the feet and proceeding in due order, one should perform it according to rule, accompanied by repeated chanting of the names of Viṣṇu.
This verse is not describing pralaya directly; it emphasizes devotional order and ritual discipline—centering the practitioner on Nārāyaṇa through a structured vow and continuous Viṣṇu-name recitation.
It presents a practical dharma for householders (and rulers as exemplary householders): undertaking regulated vratas and sustaining bhakti through Viṣṇu-nāma kīrtana, reinforcing self-governance, purity, and public religious standards.
Ritually, it stresses vidhivat performance and a sequence “from the feet onward,” suggesting a prescribed order of worship/nyāsa or limb-wise veneration—useful for understanding procedural rules that also underpin temple-ritual standardization in Puranic practice.
