देवस्वापदिनादौ तु यावत्पवित्रद्वादशी । पवित्रद्वादशीपूर्वं यावच्छ्रवणद्वादशी
devasvāpadinādau tu yāvatpavitradvādaśī | pavitradvādaśīpūrvaṃ yāvacchravaṇadvādaśī
ଦେବସ୍ୱାପ ଦିନରୁ ପବିତ୍ରା ଦ୍ୱାଦଶୀ ପର୍ଯ୍ୟନ୍ତ; ଏବଂ ପବିତ୍ରା ଦ୍ୱାଦଶୀ ପୂର୍ବରୁ ଶ୍ରବଣ ଦ୍ୱାଦଶୀ ପର୍ଯ୍ୟନ୍ତ—ଏହି ହେଉଛି ଉକ୍ତ ବ୍ରତକାଳ।
Skanda (deduced from Nāgarakhaṇḍa māhātmya-style instruction)
Scene: A priest-devotee points to a pañcāṅga (lunar almanac) showing Dvādaśī marks; nearby, a small Viṣṇu icon rests as if in yoganidrā (Devasvāpa), while devotees prepare pavitra garlands for Pavitrā Dvādaśī.
Sacred vows are not only about austerity; they are also about correct timing aligned with Viṣṇu’s ritual calendar.
This verse is calendrical (kāla-nirdeśa) and does not name a specific tīrtha.
The verse specifies vrata timing around Devaśayana/Devasvāpa and key Dvādaśī observances (Pavitrā Dvādaśī, Śravaṇa Dvādaśī).
