rājanya-kalpa-varṣādyā upadevā-sutā daśa vasu-haṁsa-suvaṁśādyāḥ śrīdevāyās tu ṣaṭ sutāḥ
Daripada Upadevā, Vasudeva memperoleh sepuluh putera, dengan Rājanya, Kalpa dan Varṣa sebagai yang utama. Daripada Śrīdevā, isteri yang lain, lahir enam putera seperti Vasu, Haṁsa dan Suvaṁśa.
It states that Upadevā had ten sons (beginning with Rājanya, Kalpa, and Varṣa) and Śrīdevā had six sons (beginning with Vasu, Haṁsa, and Suvaṁśa).
He is narrating the dynastic lineages (vaṁśa) that form the historical and devotional backdrop for the Lord’s appearances and the devotees’ stories in the Bhagavatam.
By seeing the Bhagavatam as a continuous sacred tradition—remembering that bhakti is carried through generations—and by cultivating gratitude and faith in the paramparā that preserves devotion.
