Pṛthu Mahārāja was blessed by the saintly persons present at the meeting to have a long life because of his unflinching faith and his devotion to the Supreme Personality of Godhead. Although one's duration of life is limited in years, if by chance one becomes a devotee, he surpasses the duration prescribed for his life; indeed, sometimes yogīs die according to their wish, not according to the laws of material nature. Another feature of a devotee is that he lives forever because of his infallible devotion to the Lord. It is said, kīrtir yasya sa jīvati: "One who leaves a good reputation behind him lives forever." Specifically, one who is reputed as a devotee of the Lord undoubtedly lives forever. When Lord Caitanya Mahāprabhu was talking with Rāmānanda Rāya, Caitanya Mahāprabhu inquired, "What is the greatest reputation?" Rāmānanda Rāya replied that a person who is reputed as a great devotee has the greatest reputation, for a devotee not only lives forever in the Vaikuṇṭha planets, but by his reputation he also lives forever within this material world.
(Srimad Bhagavatam------4:21:48------purport).

Śrī Caitanya Mahāprabhu then asked Rāmānanda Rāya, “Out of all glorious activities, which is the most glorious?” Rāmānanda Rāya replied, “That person who is reputed to be a devotee of Lord Kṛṣṇa enjoys the utmost fame and glory.” The greatest reputation a living being can have is to be a devotee of Kṛṣṇa and to act in Kṛṣṇa consciousness. In the material world everyone is trying to be famous by accumulating a large bank balance or material opulence. There is a steady competition among karmīs attempting to advance in a wealthy society. The whole world is turning in accordance with that competitive mood. But this kind of name and fame is temporary, for it lasts only as long as the temporary material body exists. One may become famous as a brahma-jñānī, an impersonalist scholar, or one may become a materially opulent person. In either case, such reputations are inferior to the reputation of Kṛṣṇa’s devotee.
