Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
संध्यामौनं ततः कृत्वा समान्ते घृतकुम्भकम् वस्त्रयुग्मं तिलान्घण्टां ब्राह्मणाय निवेदयेत् //
saṃdhyāmaunaṃ tataḥ kṛtvā samānte ghṛtakumbhakam vastrayugmaṃ tilānghaṇṭāṃ brāhmaṇāya nivedayet //
Having then observed silence during the Sandhyā rite, at its conclusion one should present to a brāhmaṇa a pot of ghee (ghṛta), a pair of garments, and sesame together with a bell.
This verse does not address pralaya; it focuses on daily ritual discipline (Sandhyā) and the merit-bearing act of dāna (gifting) to a brāhmaṇa.
It presents a householder-style duty: after completing Sandhyā with disciplined silence, one should conclude with a concrete act of generosity—offering ghee, cloth, sesame, and a bell to a qualified brāhmaṇa.
The significance is ritual rather than architectural: Sandhyā is to be completed with mauna (silence) and followed by prescribed dāna items—ghṛta (for offerings/lamps), vastra (ritual purity), tila (piṇḍa/śrāddha and expiatory usage), and ghaṇṭā (temple/ritual bell).
