Matsya Purana — Hiranyakashipu’s Boons
उपचेरुर्महादैत्यं हिरण्यकशिपुं तदा दिव्यतानेन गीतानि जगुर् गन्धर्वसत्तमाः //
upacerurmahādaityaṃ hiraṇyakaśipuṃ tadā divyatānena gītāni jagur gandharvasattamāḥ //
Then the foremost Gandharvas paid court to the great Daitya Hiraṇyakaśipu, singing songs in a celestial melody.
This verse does not address pralaya directly; it depicts courtly homage—celestial musicians (Gandharvas) honoring Hiraṇyakaśipu—showing worldly grandeur rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic theme of royal protocol—attendants offering praise and performance at court—highlighting ideals (and cautions) around power, reputation, and the culture of honoring rulers.
No explicit Vāstu or temple-architecture rule appears here; the ritual element is limited to celebratory court performance—formal praise through sacred-style music by Gandharvas.
