Diti’s Puṁsavana Vow, Indra’s Intervention, and the Birth of the Maruts
नाधौतपादाप्रयता नार्द्रपादा उदक्शिरा: । शयीत नापराङ्नान्यैर्न नग्ना न च सन्ध्ययो: ॥ ५१ ॥
nādhauta-pādāprayatā nārdra-pādā udak-śirāḥ śayīta nāparāṅ nānyair na nagnā na ca sandhyayoḥ
未洗净双足、未自净者,不可卧躺;双足潮湿亦不可卧;头不可朝北或朝西而眠。不可裸卧,不可与他女同卧,亦不可在日出与日落之际卧睡。
This verse advises avoiding sleeping during the two sandhyās and maintaining purity and proper conduct, treating these junction times as spiritually significant.
Diti sought a boon and observance for her purpose; Kaśyapa therefore prescribed disciplined conduct and purity rules so the vow would be properly protected and spiritually regulated.
Keep personal cleanliness before rest, maintain respectful marital boundaries, and reserve dawn/dusk for calmness, prayer, or mindful routine rather than indulgence or negligence.
