Srimad Bhagavatam Canto 04, Chapter 21, Text 44

SB 4.21.44

gunayanam sila-dhanam krta-jñam
 vrddhasrayam samvrnate ’nu sampadah
prasidatam brahma-kulam gavam ca
 janardanah sanucaras ca mahyam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
Whoever acquires the brahminical qualifications — whose only wealth is good behavior, who is grateful, and who takes shelter of experienced persons — gets all the opulence of the world. I therefore wish that the Supreme Personality of Godhead and His associates be pleased with the brahmana class, with the cows and with me.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
The Supreme Personality of Godhead is worshiped with the prayer namo brahmanya-devaya go-brahmana-hitaya ca. Thus it is clear that the Supreme Personality of Godhead respects and protects the brahmanas and brahminical culture, as well as the cows; in other words, wherever there are brahmanas and brahminical culture, there are cows and cow protection. In a society or civilization in which there are no brahmanas or brahminical culture, cows are treated as ordinary animals and slaughtered, at the sacrifice of human civilization. The specific mention of the word gavam by Prthu Maharaja is significant because the Lord is always associated with cows and His devotees. In pictures Lord Krsna is always seen with cows and His associates such as the cowherd boys and the gopis. Krsna, the Supreme Personality of Godhead, cannot be alone. Therefore Prthu Maharaja said, sanucaras ca, indicating that the Supreme Personality of Godhead is always associated with His followers and devotees.
 
A devotee acquires all the good qualities of the demigods; he is gunayanam, the reservoir of all good qualities. His only asset is good behavior, and he is grateful. Gratitude for the mercy of the Supreme Personality of Godhead is one of the qualities of brahmanas and Vaisnavas. Everyone should feel grateful to the Supreme Personality of Godhead because He is maintaining all living entities and supplying all their necessities. As stated in the Vedas (Katha Upanisad 2.2.13), eko bahunam yo vidadhati kaman: the supreme one is supplying all necessities to the living entities. The living entity who is therefore grateful to the Supreme Personality of Godhead is certainly qualified with good characteristics.
 
The word vrddhasrayam is very significant in this verse. Vrddha refers to one who is advanced in knowledge. There are two kinds of old men: those who are advanced in years and those who are experienced in knowledge. One who is advanced in knowledge is actually vrddha (jñana-vrddha); one does not become vrddha simply by advancing in age. Vrddhasrayam, a person who takes shelter of a superior person who is advanced in knowledge, can acquire all the good qualities of a brahmana and be trained in good behavior. When one actually attains good qualities, becomes grateful for the mercy of the Supreme Personality of Godhead and takes shelter of a bona fide spiritual master, he is endowed with all opulence. Such a person is a brahmana or Vaisnava. Therefore Prthu Maharaja invokes the blessings and mercy of the Supreme Personality of Godhead, with His associates, devotees, Vaisnavas, brahmanas and cows.
