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
以此礼拜之法,贞洁的妻子应连续奉行十二个月,即满一年。待一年期满,于迦尔提迦月的满月之日应守斋禁食,以作终结。
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.
