Śrīmad-Bhāgavatam
[Canto 4, Ch. 21]
who is advanced in knowledge is actually  vṛddha  ( jñāna-vṛddha ); one does not become  vṛddha  simply by advancing in age.  Vṛddhāśrayam , a person who takes shelter of a superior person who is advanced in knowledge, can acquire all the good qualities of a  brāhmaṇa  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  brāhmaṇa  or  Vaiṣṇava . Therefore  Pṛthu Mahārāja  invokes the blessings and mercy of the Supreme Personality of Godhead, with His associates, devotees,  Vaiṣṇavas ,  brāhmaṇas  and cows.
