Pitṛgaṇa-Vibhāga (Classification of the Pitṛs) and the Śrāddha–Soma Nourishment Cycle
सा तथोक्ता तदापर्णा देवी दुश्चरचारिणी / उमेति हि महाभागा त्रिषु लोकेषु विश्रुता
sā tathoktā tadāparṇā devī duścaracāriṇī / umeti hi mahābhāgā triṣu lokeṣu viśrutā
Thus addressed, the Goddess who practiced arduous austerity was then called “Aparṇā”; and that most fortunate one is renowned in the three worlds as “Umā” as well.
