tvam hi brahma-vidam sresthah
samskaran kartum arhasi
balayor anayor nrnam
janmana brahmano guruh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My lord, you are the best of the brahmanas, especially because you are fully aware of the jyotih-sastra, the astrological science. Therefore you are naturally the spiritual master of every human being. This being so, since you have kindly come to my house, kindly execute the reformatory activities for my two sons.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead, Krsna, says in Bhagavad-gita (4.13), catur-varnyam maya srstam guna-karma-vibhagasah: the four varnas — brahmana, ksatriya, vaisya and sudra must be present in society. The brahmanas are required for the guidance of the whole society. If there is no such institution as varnasrama-dharma and if human society has no such guide as the brahmana, human society will be hellish. In Kali-yuga, especially at the present moment, there is no such thing as a real brahmana, and therefore society is in a chaotic condition. Formerly there were qualified brahmanas, but at present, although there are certainly persons who think themselves brahmanas, they actually have no ability to guide society. The Krsna consciousness movement is therefore very much eager to reintroduce the varnasrama system into human society so that those who are bewildered or less intelligent will be able to take guidance from qualified brahmanas.
Brahmana means Vaisnava. After one becomes a brahmana, the next stage of development in human society is to become a Vaisnava. People in general must be guided to the destination or goal of life, and therefore they must understand Visnu, the Supreme Personality of Godhead. The whole system of Vedic knowledge is based on this principle, but people have lost the clue (na te viduh svartha-gatim hi visnum), and they are simply pursuing sense gratification, with the risk of gliding down to a lower grade of life (mrtyu-samsara-vartmani). It doesn’t matter whether one is born a brahmana or not. No one is born a brahmana; everyone is born a sudra. But by the guidance of a brahmana and by samskara, one can become dvija, twice-born, and then gradually become a brahmana. Brahmanism is not a system meant to create a monopoly for a particular class of men. Everyone should be educated so as to become a brahmana. At least there must be an opportunity to allow everyone to attain the destination of life. Regardless of whether one is born in a brahmana family, a ksatriya family or a sudra family, one may be guided by a proper brahmana and be promoted to the highest platform of being a Vaisnava. Thus the Krsna consciousness movement affords an opportunity to develop the right destiny for human society. Nanda Maharaja took advantage of the opportunity of Garga Muni’s presence by requesting him to perform the necessary reformatory activities for his sons to guide Them toward the destination of life.
