The first is Viveka. It is a very curious thing, especially to people of the West. It means, according to Ramanujha, "discrimination of food". Food contains all the energies that go to make up the forces of our body and mind. it has been transferred, and conserved, and given new directions in my body, but my body and mind have nothing essentially different from the food that I ate. Just as the force and matter we find in the material world become body and mind in us, so, essentially, the difference between body and mind and the food we eat is only in manifestation. It being so, that out of the material particles of our food we construct the instrument of thought, and that from the finer forces lodged in these particles we manufacture thought itself, it naturally follows, that both this thought and the instrument will be modified by the food we take. There are certain kinds of food that produce a certain change in the mind. we see it every day. There are other sorts which produce a change in the body, and in the long run have a tremendous effect on the mind. It is a great thing to learn. a good deal of the misery we suffer is occasioned by the food we take. You find that after a heavy and indigestible meal it is very hard to control the mind. it is running, running all the time. There are certain foods which are exciting. if you eat such food, you find that you cannot control the mind. It is obvious that after drinking a large quantity of wine, or other alcoholic beverage, a man finds that his mind would not be controlled. it runs away from his control.
