Paramparā of the Atharva Veda and Purāṇas; Definition of a Purāṇa
Daśa-lakṣaṇam
राज्ञां ब्रह्मप्रसूतानां वंश त्रैकालिकोऽन्वय: । वंशानुचरितं तेषां वृत्तं वंशधराश्च ये ॥ १६ ॥
rājñāṁ brahma-prasūtānāṁ vaṁśas trai-kāliko ’nvayaḥ vaṁśānucaritaṁ teṣāṁ vṛttaṁ vaṁśa-dharās ca ye
Dynasties are lines of kings originating with Lord Brahmā and extending continuously through past, present and future. The accounts of such dynasties, especially of their most prominent members, constitute the subject of dynastic history.
This verse states that the Bhāgavatam traces the succession of kings originating from Brahmā through all three phases of time—past, present, and future—along with their histories and descendants.
He presents dynastic lines to show the continuity of dharma through time, to situate sacred events in a historical framework, and to highlight how righteous and unrighteous conduct shapes generations.
It encourages responsibility across generations—seeing how values, leadership, and character leave lasting results—and inspires one to uphold dharma and devotion as a legacy.
