The reason why man does not know is not that he is incapable of knowing, it is only that he has so many things on his mind. He has lost his reason, power of concentration, his power of stilling the mind, and in that respect he becomes worse than the horses, dogs, and cats. No doubt as human nature he is the most active among all the creatures, and this activity is the right thing for him if he could keep it under control. Instead of that, life is made artificial, and every day it becomes increasingly artificial. A man has not remained a man, he has become a machine. His thought, his mind is constantly working, and for what? For nothing. Think of the feeling that one gets in the large cities today. The trams running and the busses, the motor-cars running over one another. Under the ground there are vibrations going on, and on the earth there are automobiles running.
