When Srila Vyasa Dev was compiling the Vedas he was confronted with some dissatisfaction of mind. Just at that moment he was visited by his Spiritual Master Jagat Guru Srila Narada Muni who advised him in many ways as to what to write that would benefit souls who are searching for enlightenment in the coming age. The following commentary is found in the Original Srimad Bhagwatam (1.6.11) translated from Sanskrit to English by A.C Bhaktivedanta Swami.
Man's activities in the fields of agriculture, mining, farming, industries, gardening all were on the same scale, as they are now, even previous to the present creation and the same activities will remain as they are even in the next creation. After many hundreds of crores of years one creation is annihilated and after many hundreds of crores of years another creation is started by the law of nature and the history of the universe repeats itself practically on the same level but the mundane wranglers waste time in the matter of archaeological excavations without any search into the vital necessities of life. Śrī Nārada Muni, even though he was a mere child, after getting an impetus of spiritual renaissance did not waste time for a single moment in the matter of economic development although he passed on through the societies of towns and villages, mines and industries but continually went on for progressive spiritual emancipation. Śrīmad-Bhāgwatam is nothing but another repeating of history which happened some hundreds of crores of years before. As it is said herein before that in the Srimad Bhagwatam only the most important factors of history, historical narration are picked up so it is recorded in this transcendental piece of literature.
* 1 Crore equals 10 million
* Srimad Bhagwatam is the ripened fruit of the tree of Vedic Knowledge.
