Matsya Purana — Vrata-Ṣaṣṭhī: The Sixty Sacred Vows
अयनादयनं यावद् वर्जयेत्पुष्पसर्पिषी तदन्ते पुष्पदामानि घृतधेन्वा सहैव तु //
ayanādayanaṃ yāvad varjayetpuṣpasarpiṣī tadante puṣpadāmāni ghṛtadhenvā sahaiva tu //
From one ayana (half-year) until the next, one should abstain from offerings of flowers and ghee (sarpis). At the completion of that period, one should offer garlands of flowers together with a ghṛta-dhenu—a cow-donation symbolically endowed with ghee.
This verse is not about Pralaya; it focuses on a timed religious observance tied to the solar half-year (ayana) and prescribes abstention and a concluding offering.
It frames dharmic discipline as time-bound restraint (avoiding certain offerings for a set period) followed by meritorious giving (garlands and a ghṛta-dhenū), aligning with householder/royal duties of vow-keeping and charitable dāna.
The significance is ritual rather than architectural: it sets an ayana-based rule of abstention and specifies the concluding pūjā/dāna items—flower garlands and the ghṛta-dhenū—typical of Matsya Purana-style vrata completion rites.
