The Future Manus and the Avatāras in Their Manvantaras
राजंश्चतुर्दशैतानि त्रिकालानुगतानि ते । प्रोक्तान्येभिर्मित: कल्पो युगसाहस्रपर्यय: ॥ ३६ ॥
rājaṁś caturdaśaitāni tri-kālānugatāni te proktāny ebhir mitaḥ kalpo yuga-sāhasra-paryayaḥ
O King, I have described to you the fourteen Manus of past, present, and future. The total span of their rule equals one thousand yuga cycles; this is called a kalpa, one day of Lord Brahmā.
Thus end the Bhaktivedanta purports of the Eighth Canto, Thirteenth Chapter, of the Śrīmad-Bhāgavatam, entitled “Description of Future Manus.”
This verse states that a kalpa (a day of Brahmā) is measured through the succession of fourteen Manus and is defined as a complete cycle of one thousand yugas.
In the context of describing manvantaras and future Manus (Canto 8, Chapter 13), Śukadeva summarizes that these fourteen Manus span the three divisions of time and together define the measure of a kalpa.
Reflecting on vast cosmic cycles helps cultivate humility and detachment, encouraging one to prioritize bhakti and dharma over temporary worldly anxieties.
