…you should put forward your most earnest efforts toward the acquisition of science and arts. The greater your attainment, the higher your standard in the divine purpose. The man of science is perceiving and endowed with vision, whereas he who is ignorant and neglectful of this development is blind. The investigating mind is attentive, alive; the callous and indifferent mind is deaf and dead. A scientific man is a true index and representative of humanity, for through processes of inductive reasoning and research he is informed of all that appertains to humanity, its status, conditions and happenings. He studies the human body politic, understands social problems and weaves the web and texture of civilization. In fact, science may be likened to a mirror wherein the infinite forms and images of existing things are revealed and reflected. It is the very foundation of all individual and national development. Without this basis of investigation, development is impossible. Therefore, seek with diligent endeavour the knowledge and attainment of all that lies within the power of this wonderful bestowal.
