Tithi-vicara
Determination of Tithi for Fasts, Parana, and Pitri Rites
उपोष्या द्वादशी पुण्या त्रयोदश्यां तु पारणम् । एकादश्यां तु विद्धायां संप्राप्ते श्रवणे तथा ॥ ३० ॥
upoṣyā dvādaśī puṇyā trayodaśyāṃ tu pāraṇam | ekādaśyāṃ tu viddhāyāṃ saṃprāpte śravaṇe tathā || 30 ||
يُصام يوم دْفادَشي (Dvādaśī) المقدّس صومَ أوبافاسا، ويكون فَكُّ الصوم (pāraṇa) في يوم تْرَيودَشي (Trayodaśī). وكذلك إذا كانت إيكادَشي (Ekādaśī) «فيدّها» (مخترَقة بتِثي مجاور) وإذا حضر نجم شرافَنا (Śravaṇa nakṣatra)، فالحكم واحد.

Vrata: Dvādaśī-vrata (with Ekādaśī-viddhā consideration)
Primary Rasa: shanta
Secondary Rasa: bhakti
It stresses that the merit of an Ekādaśī-related vrata depends not only on devotion but also on correct observance—fasting on the proper day (Dvādaśī here) and completing it with pāraṇa at the proper time (Trayodaśī), protecting the vow’s sanctity.
Bhakti is expressed through disciplined vrata-practice: fasting, restraint, and timely pāraṇa performed with reverence. The verse implies that devotion is strengthened when worship is aligned with dharmic procedure rather than personal convenience.
It highlights Jyotiṣa/Vedāṅga-based calendrical rules: tithi determination (Ekādaśī, Dvādaśī, Trayodaśī), the concept of viddhā (tithi ‘piercing’/overlap affecting eligibility), and nakṣatra consideration (Śravaṇa) for deciding vrata timing and pāraṇa.
