Manvantaras and Indras; Sudharmā’s Liberation through Viṣṇu-Pradakṣiṇā; Supremacy of Hari-Bhakti
दशमो ब्रह्मसावर्णिर्द्धर्मसावर्णिकस्ततः । ततस्तु रुद्रसावर्णी रोचमानस्ततः स्मृतः ॥ २२ ॥
daśamo brahmasāvarṇirddharmasāvarṇikastataḥ | tatastu rudrasāvarṇī rocamānastataḥ smṛtaḥ || 22 ||
দশম ব্রহ্মসাবৰ্ণি; তাৰ পিছত ধৰ্মসাবৰ্ণিক। তাৰপিছত ৰুদ্ৰসাবৰ্ণি, আৰু তাৰ পিছত ৰোচমান মনু স্মৃত॥২২॥
Sanatkumara (in dialogue with Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It preserves the Purāṇic map of cosmic time (manvantaras), showing that dharma and governance of the world proceed in ordered cycles under successive Manus.
Indirectly: by situating human religious life within manvantara cycles, it implies that bhakti and dharma are perennial and reappear across ages under different cosmic administrations.
Primarily Itihāsa–Purāṇa style chronology (useful for traditional calendrical and cosmological reckoning); it is not a direct teaching of a Vedāṅga like Vyākaraṇa or Jyotiṣa in this verse.
