Puṁsavana / Viṣṇu-vrata: Worship of Lakṣmī-Nārāyaṇa for Auspicious Progeny and Fortune
कन्या च विन्देत समग्रलक्षणं पतिं त्ववीरा हतकिल्बिषां गतिम् । मृतप्रजा जीवसुता धनेश्वरी सुदुर्भगा सुभगा रूपमग्र्यम् ॥ २६ ॥ विन्देद्विरूपा विरुजा विमुच्यते य आमयावीन्द्रियकल्यदेहम् । एतत्पठन्नभ्युदये च कर्म- ण्यनन्ततृप्ति: पितृदेवतानाम् ॥ २७ ॥ तुष्टा: प्रयच्छन्ति समस्तकामान् होमावसाने हुतभुक् श्रीहरिश्च । राजन् महन्मरुतां जन्म पुण्यं दितेर्व्रतं चाभिहितं महत्ते ॥ २८ ॥ नैवोद्विजे पर दुरत्ययवैतरण्या- स्त्वद्वीर्यगायनमहामृतमग्नचित्त: । शोचे ततो विमुखचेतस इन्द्रियार्थ- मायासुखाय भरमुद्वहतो विमूढान् ॥ ४३ ॥

If an unmarried girl observes this vrata, she will be able to get a very good husband. If a woman who is avīrā — who has no husband or son — executes this ritualistic ceremony, she can be promoted to the spiritual world. A woman whose children have died after birth can get a child with a long duration of life and also become very fortunate in possessing wealth. If a woman is unfortunate she will become fortunate, and if ugly she will become beautiful. By observing this vrata, a diseased man can gain relief from his disease and have an able body with which to work. If one recites this narration while offering oblations to the pitās and demigods, especially during the śrāddha ceremony, the demigods and inhabitants of Pitṛloka will be extremely pleased with him and bestow upon him the fulfillment of all desires. After one performs this ritualistic ceremony, Lord Viṣṇu and His wife, mother Lakṣmī, the goddess of fortune, are very pleased with him. O King Parīkṣit, now I have completely described how Diti performed this ceremony and had good children — the Maruts — and a happy life. I have tried to explain this to you as elaborately as possible.
Thus end the Bhaktivedanta purports of the Sixth Canto, Nineteenth Chapter, of the Śrīmad-Bhāgavatam, entitled “Performing the Puṁsavana Ritualistic Ceremony.”
