Matsya Purana — The Observance of Ananta-Tritiya
नभस्ये पूजयेद्गौरीम् उत्पलैरसितैः सदा बन्धुजीवैराश्वयुजे कार्त्तिके शतपत्त्रकैः //
nabhasye pūjayedgaurīm utpalairasitaiḥ sadā bandhujīvairāśvayuje kārttike śatapattrakaiḥ //
In the month of Nabhasya (Bhādrapada), one should always worship Goddess Gaurī with dark-blue lotuses; in Āśvayuja (Āśvina) with bandhujīva flowers; and in Kārttika with śatapattraka (hundred-petalled) flowers.
This verse is not about pralaya; it belongs to a ritual-calendar context, prescribing month-wise floral offerings for Gaurī worship.
It supports the householder’s (and ruler’s) dharma by giving a disciplined, time-specific pūjā routine—monthly observances with appropriate offerings, emphasizing regular devotion and ritual correctness.
The significance is ritual (pūjā-vidhi): selecting seasonally appropriate flowers for worship—dark utpala in Bhādrapada, bandhujīva in Āśvina, and many-petalled flowers in Kārttika—reflecting a structured liturgical calendar.
