आश्विनस्य च मासस्य नवरात्रे विशेषतः । उपोष्य चैकभक्तैर्वा देवीस्त्वेताः प्रपूजयेत्
āśvinasya ca māsasya navarātre viśeṣataḥ | upoṣya caikabhaktairvā devīstvetāḥ prapūjayet
विशेषकर आश्विन मास की नवरात्रि में, उपवास करके अथवा एकभक्त-व्रत (एक बार भोजन) का पालन करते हुए, इन देवियों की विशेष श्रद्धा से पूजा करनी चाहिए।
Lomaharṣaṇa Sūta (deduced: Māheśvarakhaṇḍa narrative voice)
Tirtha: Navatīrtha (Devī-kṣetra)
Type: kshetra
Scene: Navarātra nights in a tīrtha-town: devotees with fasting discipline, lamps in rows, Devī icons adorned, offerings arranged; a sense of heightened sacred time.
Seasonal sacred time (kāla) intensifies merit: disciplined worship in Navarātra yields heightened auspicious results.
The same nava-tīrtha region where these Devīs are established; the verse focuses on the time for worship rather than naming a new site.
Navarātra pūjā in Āśvina with either upavāsa (fasting) or eka-bhakta (one meal a day) observance.
