Matsya Purana — The Rite and Glory of Meru-Dāna: The Tenfold ‘Gift of Meru’ and Mountain-Offe...
वितानकं चोपरि पञ्चवर्णम् अम्लानपुष्पाभरणं सितं च इत्थं निवेश्यामरशैलमग्र्यं मेरोस्तु विष्कम्भगिरीन् क्रमेण //
vitānakaṃ copari pañcavarṇam amlānapuṣpābharaṇaṃ sitaṃ ca itthaṃ niveśyāmaraśailamagryaṃ merostu viṣkambhagirīn krameṇa //
Above it one should place a five-coloured canopy, and adorn it with white garlands of unfading flowers. Thus, having duly set up the foremost divine mountain, Amaraśaila, one should then arrange in proper sequence the supporting mountains of Meru.
This verse is not about Pralaya; it focuses on cosmographic/ritual arrangement—how the divine mountain and Meru’s supporting ranges are to be set out in ordered fashion.
It reflects the duty to uphold dharma through correct ritual order and sacred layout—commissioning or performing rites with proper materials (canopy, pure white unfading garlands) and correct sequence, which is a householder/royal responsibility in Purāṇic practice.
It specifies ritual-architectural decor: a five-coloured canopy (vitāna) placed above, white unfading floral adornments, and a prescribed sequential placement of Meru’s supporting mountains—language closely aligned with Vastu/installation procedures.
