विद्यते सा त्वखंडा स्यान्न्यूना चेत्खंडसंज्ञिता । तिथेः पंचदशो भागः क्रमात्प्रतिपदादयः ॥ १५५ ॥
vidyate sā tvakhaṃḍā syānnyūnā cetkhaṃḍasaṃjñitā | titheḥ paṃcadaśo bhāgaḥ kramātpratipadādayaḥ || 155 ||
បើតិថីមានពេញលេញ នោះហៅថា «អខណ្ឌា» (akhaṇḍā) គឺមិនបែកបាក់; បើខ្វះខាត នោះហៅថា «ខណ្ឌ» (khaṇḍa) គឺបែកបាក់។ តិថីគឺជាផ្នែកទីដប់ប្រាំនៃខែចន្ទគតិ ដោយចាប់ផ្តើមតាមលំដាប់ពី ប្រតិបទា (Pratipadā) និងបន្តទៅទៀត។
Narada (teaching in a technical context of tithi computation)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It grounds spiritual practice in correct sacred time (kāla): vows and worship gain steadiness when performed on a properly determined tithi, distinguishing complete (akhaṇḍā) from deficient (khaṇḍa).
Bhakti is expressed through disciplined observances (vrata, pūjā) done at the right tithi; this verse supplies the time-rule so devotional acts align with dharmic order.
Jyotiṣa Vedāṅga (calendar science): a tithi is defined as one of fifteen parts, and the verse notes the technical distinction between akhaṇḍā and khaṇḍa tithi used in Panchanga-based ritual scheduling.
