Puṁsavana / Viṣṇu-vrata: Worship of Lakṣmī-Nārāyaṇa for Auspicious Progeny and Fortune
एतेन पूजाविधिना मासान् द्वादश हायनम् । नीत्वाथोपरमेत्साध्वी कार्तिके चरमेऽहनि ॥ २१ ॥
etena pūjā-vidhinā māsān dvādaśa hāyanam nītvāthoparamet sādhvī kārtike carame ’hani
By this method of worship, the chaste wife should continue the devotional service for twelve months, completing a full year. When the year has passed, on the full-moon day of the month of Kārttika, she should fast and bring the vow to its conclusion.
This verse states it should be followed for twelve months—one full year—using the described worship procedure.
It should be concluded on the final day of the month of Kārtika.
It teaches disciplined, time-bound devotion—commit to a consistent sādhana for a set period and complete it properly rather than practicing irregularly.
