Matsya Purana — Soma
गृहमेधिनश्च यज्वानो ह्य् अग्निष्वात्तार्तवाः स्मृताः अष्टकापतयः काव्याः पञ्चाब्दांस्तु निबोधत //
gṛhamedhinaśca yajvāno hy agniṣvāttārtavāḥ smṛtāḥ aṣṭakāpatayaḥ kāvyāḥ pañcābdāṃstu nibodhata //
Householders who have performed sacrifices are remembered as the Agniṣvātta Pitṛs—also called Ārtavas. Know further: the Kāvya Pitṛs are the lords of the Aṣṭakā rites, and their period is five years.
This verse is not about cosmic dissolution; it classifies ancestral beings (Pitṛs) and links them to specific rites and time-cycles, indicating how ritual order continues regardless of larger cosmological themes.
It frames gṛhasthas who perform yajñas as connected with the Agniṣvātta/Ārtava Pitṛs, underscoring that a householder’s sacrificial life and ancestral rites (like Aṣṭakā/Śrāddha) are core duties of dharma.
The significance is ritual: it identifies the Kāvya Pitṛs as presiding over the Aṣṭakā rites and notes a five-year cycle/measure, useful for understanding Purāṇic scheduling and categorization of śrāddha-related observances.
