Matsya Purana — Code of Conduct and Vow-Procedure for Courtesans
नमो नारायणायेति कामदेवात्मने नमः सर्वशान्त्यै नमः प्रीत्यै नमो रत्यै नम श्रियै //
namo nārāyaṇāyeti kāmadevātmane namaḥ sarvaśāntyai namaḥ prītyai namo ratyai nama śriyai //
“Salutations—‘Obeisance to Nārāyaṇa!’ Homage to Him whose very nature is Kāma (the divine power of desire). Salutations to universal Peace; salutations to Affection; salutations to Love; salutations to Śrī (Prosperity).”
Indirectly, it frames Nārāyaṇa as the sustaining cosmic principle: peace (śānti), prosperity (śrī), and the motivating force of desire (kāma) are invoked as divine powers that uphold order even across cycles of creation and dissolution.
It presents a value-map for righteous life: the king/householder should cultivate śānti (social harmony), prīti (benevolence), regulated rati (lawful enjoyment within dharma), and śrī (well-earned prosperity), all anchored in devotion to Nārāyaṇa.
Ritually, it functions as a stuti/mantra-style salutation suitable for japa or pūjā openings; while not a Vāstu rule itself, it aligns temple/ritual intent toward śānti and śrī—standard aims invoked before consecratory acts.
