Pitṛgaṇa-Vibhāga (Classification of the Pitṛs) and the Śrāddha–Soma Nourishment Cycle
एति श्रीब्रह्माण्डे महापुराणे वायुप्रोक्ते मध्यभागे तृतीय उपोद्धातपादे पितृकल्पो नाम नवमो ऽध्यायः // ९// बृहस्पतिरुवाच सप्तैते जयतां श्रेष्ठाः स्वर्गे पितृगणाः स्मृताः / चत्वारो मुर्त्तिमन्तश्च त्रयस्तेषाममूर्त्तयः
eti śrībrahmāṇḍe mahāpurāṇe vāyuprokte madhyabhāge tṛtīya upoddhātapāde pitṛkalpo nāma navamo 'dhyāyaḥ // 9// bṛhaspatiruvāca saptaite jayatāṃ śreṣṭhāḥ svarge pitṛgaṇāḥ smṛtāḥ / catvāro murttimantaśca trayasteṣāmamūrttayaḥ
Thus, in the holy Brahmāṇḍa Mahāpurāṇa, spoken by Vāyu, in the middle section, within the third Upoddhāta-pāda, is the ninth chapter called “Pitṛkalpa.” Bṛhaspati said: In heaven these seven hosts of the Pitṛs are remembered as the foremost among the victorious; four are embodied, and three are without form.
