(His Divine Grace A.C. Bhaktivedanta Swami Prabhupada)
"Śrīman Rāmānanda Rāya came again to see the Lord the next evening, and there were further discourses on this transcendental subject matter.
'What is the highest standard of education?' Lord Caitanya began His inquiry, and Rāmānanda Rāya immediately replied that the highest standard of education is knowledge of the science of Kṛṣṇa. The standard of material education is sense gratification, but the highest standard of spiritual education is knowledge of the science of Kṛṣṇa. In Śrīmad-Bhāgavatam (4.29.50) it is stated that that work which pleases the Supreme Personality of Godhead is the highest work, and that science or knowledge which places one in full Kṛṣṇa consciousness is the highest knowledge. Similarly, Prahlāda Mahārāja, while instructing his childhood friends at school, also stated that hearing of the Lord, chanting, remembering, worshiping, praying, serving, making friends with Kṛṣṇa, and offering everything to Him constituted the highest spiritual knowledge.
'And what is the greatest reputation one can have?' Lord Caitanya asked Rāmānanda Rāya, and Rāmānanda immediately replied that a person reputed to be Kṛṣṇa conscious should be considered the most famous man in the world.
One who is famous as a Kṛṣṇa conscious man enjoys eternal fame. In the material world, everyone is striving for three things: he wants his name to be perpetuated, he wants his fame to be broadcast all over the world, and he wants some profit from his material activities. But no one knows that all this material name, fame and profit belong to the temporary material body and that as soon as the body is finished, all name, fame and profit are finished also. It is only due to ignorance that everyone is striving after the name, fame and profit that are connected with the body. It is deplorable to become famous on the basis of the body or to become known as a man of spiritually developed consciousness without knowing the supreme spirit, Viṣṇu. Real fame can only be had if one attains Kṛṣṇa consciousness."
