Diti’s Puṁsavana Vow, Indra’s Intervention, and the Birth of the Maruts
सांवत्सरं पुंसवनं व्रतमेतदविप्लुतम् । धारयिष्यसि चेत्तुभ्यं शक्रहा भविता सुत: ॥ ५४ ॥
sāṁvatsaraṁ puṁsavanaṁ vratam etad aviplutam dhārayiṣyasi cet tubhyaṁ śakra-hā bhavitā sutaḥ
迦叶牟尼继续说道:若你以信心无缺地守持此名为“普姆萨瓦那”的仪式誓戒至少一年,你将诞生一子,命定诛杀因陀罗;若行持稍有差失,此子便将成为因陀罗之友。
This verse states that if the puṁsavana vow is observed without break for one full year, it can grant the desired result—here, the birth of a powerful son.
In the narrative, Diti desired a son who could kill Indra (Śakra). Kashyapa instructed her in a strict vow and explained the promised outcome if she maintained it faithfully.
The verse emphasizes consistency and purity of practice—results come when a commitment is maintained steadily and without lapses.
