The following quote from Srimad Bhagavatam 1.16.31 with purport by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada give a small indication of the importance of Lord Krsna's Vedic culture:
devan pitrn rsin sadhun
sarvan varnams tathasraman
I am thinking about myself and also, O best amongst the demigods, about you, as well as about all the demigods, sages, denizens of Pitrloka, devotees of the Lord and all men obedient to the system of varna and asrama in human society.
To effect the perfection of human life there is cooperation between men and demigods, sages, denizens of the Pitrloka, devotees of the Lord and the scientific system of varna and asrama orders of life. The distinction between human life and animal life therefore begins with the scientific system of varna and asrama, guided by the experience of the sages in relation with the demigods, gradually rising to the summit of reestablishing our eternal relation with the Supreme Absolute Truth, the Personality of Godhead, Lord Sri Krsna. When God-made varnasrama-dharma, which is strictly meant for developing animal consciousness into human consciousness and human consciousness into godly consciousness, is broken by advancement of foolishness, the whole system of peaceful and progressive life is at once disturbed. In the age of Kali, the first attack of the venomous snake strikes against the God-made varnasrama-dharma, and thus a person properly qualified as a brahmana is called a sudra, and a sudra by qualification is passing as a brahmana, all on a false birthright claim. To become a brahmana by a birthright claim is not at all bona fide, although it may be a fulfillment of one of the conditions. But the real qualification of a brahmana is to control the mind and the senses, and to cultivate tolerance, simplicity, cleanliness, knowledge, truthfulness, devotion and faith in the Vedic wisdom. In the present age, consideration of the necessary qualification is being neglected, and the false birthright claim is being supported even by a popular, sophisticated poet, the author of Rama-carita-manasa.
This is all due to the influence of the age of Kali. Thus mother earth, represented as a cow, was lamenting the regrettable condition.
