Hare Krsna,
Srila Prabhupada mentioned in his various writings that Krsna consciousness is a science – the most scientific philosophy.
“Vijñānam means it is scientific. It is not a sentiment or fanaticism. It is scientific. So try to understand this philosophy of Kṛṣṇa consciousness from Bhagavad-gītā and help yourself, help your countrymen, help the world. There will be peace and prosperity.” (Lecture on BG 8.28-9.2 — New York, November 21, 1966)
The best example is the four divisions of human society. Critics of India and its caste system accuse us that it’s a man-made division created to subjugate its subjects. Even Indians haven’t understood the caste system scientifically; they erroneously think its by birth.
Our scriptures clearly prove that the four divisions of human society are created by the Supreme Lord Himself.
BG 4.13: According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me. And, although I am the creator of this system, you should know that I am yet the non-doer, being unchangeable.
Bhagavad-Gita does not mention in detail how these four divisions originated from the Supreme Lord. Srimad-Bhagavatam explains this intricately. This is the beauty of Srimad Bhagavatam.
SB 3.6.30 — O chief of the Kuru dynasty, the Vedic wisdom became manifested from the mouth of the virāṭ, the gigantic form. Those who are inclined to this Vedic knowledge are called brāhmaṇas, and they are the natural teachers and spiritual masters of all the orders of society.
SB 3.6.31 — Thereafter the power of protection was generated from the arms of the gigantic virāṭ form, and in relation to such power the kṣatriyas also came into existence by following the kṣatriya principle of protecting society from the disturbance of thieves and miscreants.
SB 3.6.32 — The means of livelihood of all persons, namely production of grains and their distribution to the prajās, was generated from the thighs of the Lord’s gigantic form. The mercantile men who take charge of such execution are called vaiśyas.
SB 3.6.33 — Thereafter, service was manifested from the legs of the Personality of Godhead for the sake of perfecting the religious function. Situated on the legs are the śūdras, who satisfy the Lord by service.
These four divisions of human society exist in every society and country. People may call it differently or ignore it altogether. Every society and institution have intelligent class (brahmanas), administrative class (ksatriyas), trade and agriculture class (vaisyas) and worker class (sudras). Another good way to distinguish these four divisions are as follows: people who get paid for their service are sudras; people who make profits are vaisyas; people who collect taxes are ksatriyas; and people who live on charity are brahmanas. This is a very crude classification. The point I am making is that this structure of human society exists everywhere.
In this Kali-yuga, it is difficult to ascertain what our true varna is. That’s because society doesn’t function according to the varsnasrama system anymore. Varnasrama system exists but is overlooked. Sudras are trying to be administrators. Administrators do not function under the guidance of brahmanas. True Brahminical class hardly exists. Hence there is so much chaos in this world.
To keep things simple, one thing that is common to all these four divisions of human society is service.
SB 3.6.33: Service is the real constitutional occupation of all living entities. The living entities are meant to render service to the Lord, and they can attain religious perfection by this service attitude. It is clearly said here that the principle of service was generated from the legs of the Lord for the sake of perfecting the religious process, but this transcendental service is different from the idea of service in the material world. In the material world, no one wants to be a servant; everyone wants to become the master because false mastership is the basic disease of the conditioned soul. The conditioned soul in the material world wants to lord it over others. Illusioned by the external energy of the Lord, he is forced to become a servant of the material world. That is the real position of the conditioned soul.
Therefore, we have to dovetail everything to the service and pleasure of the Supreme Lord. As Krsna is transcendental to this system of the four divisions of human society, a person in Krsna consciousness is also transcendental to all divisions of human society, whether we consider the divisions of community, nation or species. As long as we remember that we are the eternal servants of the Supreme Lord and engage ourselves in that mood, we can perfect our human life. The best service recommended for this age is devotional service (bhakti-yoga) that begins with the chanting of the Holy Name.
All glories to Srila Prabhupada!
