Matsya Purana — The Maheshvara Vow: Śiva-Caturdaśī Vrata
पादौ नमः शिवायेति शिरः सर्वात्मने नमः त्रिनेत्रायेति नेत्राणि ललाटं हरये नमः //
pādau namaḥ śivāyeti śiraḥ sarvātmane namaḥ trinetrāyeti netrāṇi lalāṭaṃ haraye namaḥ //
To the feet: “obeisance to Śiva.” To the head: “obeisance to the All-Self.” To the eyes: “obeisance to the Three-eyed One.” To the forehead: “obeisance to Hara.”
It does not describe pralaya directly; it teaches inner sacralization—seeing Śiva as the “All-Self” (sarvātmā), a metaphysical view often used in Purāṇas to ground liberation beyond cosmic cycles.
It supports daily dharma through regulated worship: a householder (and by extension a king) is urged to maintain purity, self-control, and regular devotion by consecrating the body with mantra—an ethical discipline that steadies conduct and governance.
Ritually, it is an aṅga-nyāsa/karanyāsa-style mapping of mantras onto body parts, used before pūjā, japa, or temple worship to ‘install’ the deity’s presence within the practitioner.
