If the plants are acted on by various medicines and drugs like ourselves, then we can create an agent or a spokesman on which we can carry out all future investigations on the action of drugs. Then there is opened out a great vista for the scientific study of medicine. And let me tell you medicine is not yet an exact science. It is merely a phase of tradition. We have not been able to make medicine scientific. Now by the data of the influence of drugs on the fundamental basis of life, as is seen in the plant, we shall be able to make the science of medicine purely scientific. In travelling all over the world, which I have done several times, I was struck by two great characteristics of different nations. One characteristic of certain nations is living for the future. All the modern nations are striving to win force and power from nature. There is another class of men who live on the glory of the past. Now, what is to be the future of our nation? Are we to live only on the glory of the past and die off from the face of the earth, to show that we are worthy descendants of the glorious past and to show by our work, by our intellect and by our service that we are not a decadent nation? We have still a great and mighty future before us, a future that will justify our ancestry. In talking about ancestry, do we ever realise that the only way in which we can do honour to our past is not to boast of what our ancestors have done but to carry out in the future something as great, if not greater than they. Are we to be a living nation, to be proud of our ancestry and to try to win renown by continuous achievements? These mighty monuments that I see around me tell us what has been done till very recent times. I have travelled over some of the greatest ruins of the Universities of India. I have been to the ruins of the University of Taxilla in the farthest corner of India which attracted the people of the west and the east. I had been to the ruins of Nalanda, a University which invited all the west to gain knowledge under its intellectual fostering. I had been all there and seen them. I have come here also and want to visit Conjeevaram. But are you to foster the dead honours or to try to bring back your University in India and drag once more from the rest of the world people who would come down and derive knowledge from India? It is in that way and that way alone we can win our self-respect and make our life and the life of the nation worthy. The present era is the era of temples of learning. In order to erect temples of learning we require all the offerings of our mighty people. We want to erect temples and "viharas" which are so indispensable to the study of nature and her secrets. It is a problem which appeals to every thoughtful Indian. It is by the effort of the people and by their generosity that all these mighty temples arose; and now are we to worship the dead stones or are we to erect living temples
