Education must be regarded as a sacred process and preparation for unselfish service to society. There are innumerable people in the world who are suffering from various physical and other disabilities. It is the duty of educated persons to serve them and help to relieve their suffering to the maximum extent possible. This is the best form of service to the Divine. There is pollution and impurity in the air, water and in many things around us. You must use the knowledge you acquire to purify what is impure. Service to society must become the primary purpose of education. Students of Sai should devote their knowledge not only to earn a living, but to use their talents and energies in whatever walk of life they may be engaged in to render service to society in all ways open to them. (Divine Discourse, Feb 5, 1984)
