True education means trying to manifest the inner divinity in man. How is this manifestation to be brought about? Students must receive education that illumines every aspect of life - the economic, the political, the moral, the spiritual and the physical, the mental and the social environment of man. It should not be confined to one specific sphere. Many students consider book knowledge as education. This gives them only superficial knowledge. They need practical knowledge which will enable them to lead righteous lives. Education should also result in the purification of the heart. Men and women must be taught to be sincere in thought, word and deed, as a mark of humanness. Students must also revere their parents at all times and promote the cause of social improvement. They must co-operate with all fellow-beings. These are the things all students should learn.(Divine Discourse, Nov 22, 1997.)
