And now, since the war has taken place, now even the sky is not free for us to breathe the pure air; there are also aeroplanes you see every day. If you go near the water there are steaming ships making noise; if you go into the country you have the noise of the factory from morning till evening; and in the town there are machines. Impressed by all these things, if you ask a man, talk to him something about the inner voice, about spiritual ideas, he will answer, "What is it? I don't understand." It is only necessary to hear the voice which is within, it is not necessary to study something. What is necessary is to become like nature. But man has become artificial, and he must become natural in order to hear the voice within. But the unfortunate thing is that this artificial life has become necessary to man, and when they tell him about natural life, spiritual life, God ideal, natural thought, he thinks it is something against his nature; he says, "I can't bear it."
