Matsya Purana — The Ārdrānandakarī Tṛtīyā Vrata: Ritual Procedure
एवं सम्पूज्य विधिवद् अग्रतः शिवयोः पुनः पद्मोत्पलानि रजसा नानावर्णेन कारयेत् //
evaṃ sampūjya vidhivad agrataḥ śivayoḥ punaḥ padmotpalāni rajasā nānāvarṇena kārayet //
Thus, having duly completed the worship according to rite, one should again, before Śiva and Śivā, arrange lotus and blue-lotus flowers, using colored powders of various hues.
This verse does not discuss pralaya; it focuses on post-worship ritual detailing—decorative floral offerings before Śiva and Śivā.
It implies the grihastha/kingly duty of maintaining dharmic worship: performing pūjā विधिवत् (as prescribed) and offering pure, aesthetically arranged items (lotus/utpala, colored powders) as part of regular religious observance.
Ritually, it specifies an upacāra: arranging lotus and utpala with multicolored powders before the deities—guidance relevant to altar/mandala decoration and temple-pūjā ornamentation practices.
