Educational institutions today are full of disorder and indiscipline. How different were the ancient abodes of learning! In ancient times education used to be offered free. In those days, the preceptors used to send the students to the forests. The students used to be examined periodically about their studies. For instance, the students would be asked: "What tree did you find useless in the forest you visited?" The replies of the students varied, each one saying that one particular tree was useless. The preceptor did not accept their answers. He told them that all trees were useful, each in its own way. Every tree had something or the other which had medicinal properties. If a tree did nothing else, it served to take in the carbon dioxide from the atmosphere and release the life-giving oxygen for the benefit of man. Every tree serves a useful purpose. Equally every human being is valuable.
