Matsya Purana — The Aśūnyaśayana Vrata
गीतवादित्रनिर्घोषं देवदेवस्य कीर्तयेत् घण्टा भवेदशक्तस्य सर्ववाद्यमयी यतः //
gītavāditranirghoṣaṃ devadevasya kīrtayet ghaṇṭā bhavedaśaktasya sarvavādyamayī yataḥ //
One should glorify Devadeva with the resonant sounds of singing and musical instruments. If one is unable (to arrange many instruments), a bell may be used instead, for the bell is regarded as embodying the essence of all instruments.
This verse does not discuss Pralaya; it focuses on devotional worship—honoring Devadeva through sacred sound (song, instruments, or a bell).
It frames a practical dharmic duty: even without wealth or resources, a householder (or ruler) can perform worship by using a bell as a complete substitute for elaborate musical offerings.
Ritually, it elevates temple/puja sound-offerings (nāda-upacāra): if full music is not possible, the ghaṇṭā (bell) alone is acceptable because it symbolizes all instruments in worship.
