Pitṛgaṇa-Vibhāga (Classification of the Pitṛs) and the Śrāddha–Soma Nourishment Cycle
न्यग्रोधमे कपर्णा तु पाठलं त्वेकपाटला / आशिते द्वे अपर्णा तु ह्यनिकेता तपो ऽचरत्
nyagrodhame kaparṇā tu pāṭhalaṃ tvekapāṭalā / āśite dve aparṇā tu hyaniketā tapo 'carat
Ekaparṇā lived on the nyagrodha; Ekapāṭalā on the pāṭala blossom. But Aparṇā renounced both, and, without shelter, performed austerities.
