अमादिपौर्णमास्यंता या एव शशिनः कलाः । तिथयस्ताः समाख्याताः षोडशैव प्रकीर्तिताः
amādipaurṇamāsyaṃtā yā eva śaśinaḥ kalāḥ | tithayastāḥ samākhyātāḥ ṣoḍaśaiva prakīrtitāḥ
From Amā (new moon) up to the full-moon end—those very phases of the Moon are called “tithis”; they are proclaimed to be precisely sixteen.
Īśvara (Śiva)
Tirtha: Prabhāsa-kṣetra
Type: kshetra
Listener: Devī
Scene: Īśvara enumerates: the Moon’s phases from Amā to Paurṇamāsī are called tithis, exactly sixteen in number.
Sacred time is mapped onto the Moon’s kalās; observing tithis aligns human life with cosmic rhythm.
Prabhāsakṣetra is the narrative setting; the Māhātmya presents it as a place where dharma of time-observance is illuminated.
Implicitly, it supports tithi-based observances (vratas, pūjā timing), but no single rite is specified in this verse.
