Pitṛgaṇa-Vibhāga (Classification of the Pitṛs) and the Śrāddha–Soma Nourishment Cycle
मरीचि गर्भास्ते लोकाः समावृत्य दिवि स्थिताः / एते ह्यङ्गिरसः पुत्राः साध्यैः संवर्द्धिताः पुरा
marīci garbhāste lokāḥ samāvṛtya divi sthitāḥ / ete hyaṅgirasaḥ putrāḥ sādhyaiḥ saṃvarddhitāḥ purā
Those worlds, conceived in Marīci’s womb, spread forth and abide in the heavens. They are the sons of Aṅgiras, once nurtured long ago by the Sādhyas.
