brahmano brahma-varcasvi
rajanyo jagati-patiḥ
vaisyaḥ pathan vit-patiḥ syac
chūdraḥ sattamatam iyat
brahmanaḥ-the brahmanas; brahma-varcasvi-one who has attained the power of spiritual success; rajanyaḥ-the royal order; jagati-patiḥ-the king of the world; vaisyaḥ-the mercantile class of men; pathan-by reading; vit-patiḥ-becomes master of animals; syat-becomes; sūdraḥ-the laborer class of men; sattamatam-the position of a great devotee; iyat-attains.
TRANSLATION
If one hears of the characteristics of Prthu Maharaja and is a brahmana, he becomes perfectly qualified with brahminical powers; if he is a ksatriya, he becomes a king of the world; if he is a vaisya, he becomes a master of other vaisyas and many animals; and if he is a sūdra, he becomes the topmost devotee.
PURPORT
In Srimad-Bhagavatam it is recommended that one should become a devotee regardless of one's condition. Whether one is without desire (akama), or with desire (sakama), or whether one desires liberation (moksa-kama), he is advised to worship the Supreme Lord and execute devotional service unto Him. By so doing, one attains all perfection in any field of life. The process of devotional service-especially hearing and chanting-is so powerful that it can bring a person to the perfectional stage. In this verse brahmanas, ksatriyas, vaisyas and sūdras are mentioned, but here it should be understood that that reference is to the brahmana who is born in a brahminical family, the ksatriya who is born in a ksatriya family, the vaisya who is born in a vaisya family and the sūdra in a sūdra family. But whether one is a brahmana, ksatriya, vaisya or sūdra, he can attain perfection simply by hearing and chanting.
To take birth in a family of brahmanas is not the ultimate finishing touch; one must have the power of a brahmana, which is called brahma-tejas. Similarly, taking birth in a royal family is not the all in all; one must possess the power to rule the world. Similarly, taking birth as a vaisya is not all; one must possess hundreds or thousands of animals (specifically cows) and rule over other vaisyas as Nanda Maharaja did in Vrndavana. Nanda Maharaja was a vaisya who possessed 900,000 cows and ruled over many cowherd men and boys. A person who is born in a sūdra family can become greater than a brahmana simply by accepting devotional service and giving aural reception to the pastimes of the Lord and His devotees.
