Adhyaya 80 — Vaivasvata Manvantara: Enumeration of Manus and the Eighth Manu Sāvarṇi
इत्यादिकस्तु सुतपा देवानां विंशको गणः ।
प्रभुर्विभुर्विभासाद्यस्तथान्यो विंशको गणः ॥
ityādikas tu sutapā devānāṃ viṃśako gaṇaḥ / prabhur vibhur vibhāsādyas tathānyo viṃśako gaṇaḥ
Such names beginning with these constitute the Sutapā group of twenty gods. Likewise, another group of twenty begins with Prabhu, Vibhu, and Vibhāsa.
Purāṇic pedagogy often uses abbreviated list-markers (‘ityādika’) to indicate vast structured knowledge—inviting the hearer to recognize order without being burdened by exhaustive repetition.
Manvantara: cataloguing deva-hosts and their groupings is part of the manvantara profile.
The shift from one deva-group to another hints that cosmic functions are modular: different ‘sets’ of powers operate together as a unit, reflecting layered governance in subtle cosmology.
