Great personalities of the material world are very eager to render welfare service to human society, but actually no one can render better service than one who distributes the knowledge of spiritual realization in relation with the Supreme Personality of Godhead. All living entities are within the clutches of the illusory energy. Forgetting their real identity, they hover in material existence, transmigrating from one body to another in search of a peaceful life. Since these living entities have very little knowledge of self-realization, they are not getting any relief, although they are very anxious to attain peace of mind and some substantial happiness. Saintly persons like the Kumāras, Nārada, Prahlāda, Janaka, Śukadeva Gosvāmī and Kapiladeva, as well as the followers of such authorities as the Vaiṣṇava ācāryas and their servants, can render a valuable service to humanity by disseminating knowledge of the relationship between the Supreme Personality of Godhead and the living entity. Such knowledge is the perfect benediction for humanity.
Knowledge of Kṛṣṇa is such a great gift that it is impossible to repay the benefactor. Therefore Pṛthu Mahārāja requested the Kumāras to be satisfied by their own benevolent activities in delivering souls from the clutches of māyā. The King saw that there was no other way to satisfy them for their exalted activities. The word vinoda-pātram can be divided into two words, vinā and uda-pātram, or can be understood as one word, vinoda-pātram, which means "joker." A joker's activities simply arouse laughter, and a person who tries to repay the spiritual master or teacher of the transcendental message of Kṛṣṇa becomes a laughingstock just like a joker because it is not possible to repay such a debt. The best friend and benefactor of all people is one who awakens humanity to its original Kṛṣṇa consciousness.
