SB 1.5.22

Human intellect is developed for advancement of learning in art, science, philosophy, physics, chemistry, psychology, economics, politics, etc. By culture of such knowledge the human society can attain perfection of life. This perfection of life culminates in the realization of the Supreme Being, Viṣṇu. The śruti therefore directs that those who are actually advanced in learning should aspire for the service of Lord Viṣṇu. Unfortunately persons who are enamored by the external beauty of viṣṇu-māyā do not understand that culmination of perfection or self-realization depends on Viṣṇu. Viṣṇu-māyā means sense enjoyment, which is transient and miserable. Those who are entrapped by viṣṇu-māyā utilize advancement of knowledge for sense enjoyment. Śrī Nārada Muni has explained that all paraphernalia of the cosmic universe is but an emanation from the Lord out of His different energies because the Lord has set in motion, by His inconceivable energy, the actions and reactions of the created manifestation. They have come to be out of His energy, they rest on His energy, and after annihilation they merge into Him. Nothing is, therefore, different from Him, but at the same time the Lord is always different from them. When advancement of knowledge is applied in the service of the Lord, the whole process becomes absolute. The Personality of Godhead and His transcendental name, fame, glory, etc., are all nondifferent from Him. Therefore, all the sages and devotees of the Lord have recommended that the subject matter of art, science, philosophy, physics, chemistry, psychology and all other branches of knowledge should be wholly and solely applied in the service of the Lord. Art, literature, poetry, painting, etc., may be used in glorifying the Lord. The fiction writers, poets and celebrated litterateurs are generally engaged in writing of sensuous subjects, but if they turn towards the service of the Lord they can describe the transcendental pastimes of the Lord. Vālmīki was a great poet, and similarly Vyāsadeva is a great writer, and both of them have absolutely engaged themselves in delineating the transcendental activities of the Lord and by doing so have become immortal. Similarly, science and philosophy also should be applied in the service of the Lord. There is no use presenting dry speculative theories for sense gratification. Philosophy and science should be engaged to establish the glory of the Lord. Advanced people are eager to understand the Absolute Truth through the medium of science, and therefore a great scientist should endeavor to prove the existence of the Lord on a scientific basis. Similarly, philosophical speculations should be utilized to establish the Supreme Truth as sentient and all-powerful. Similarly, all other branches of knowledge should always be engaged in the service of the Lord. In the Bhagavad-gītā also the same is affirmed. All “knowledge” not engaged in the service of the Lord is but nescience. Real utilization of advanced knowledge is to establish the glories of the Lord, and that is the real import. Scientific knowledge engaged in the service of the Lord, and all similar activities, are all factually hari-kīrtana, or glorification of the Lord.
