{{Pause=2}} CHAPTER 29 {{PAUSE=1}}Danger to Cities {{Pause=2}} [Translated from notes made in November 1975] Further continuing the discussion described in Chapters 27 and 28, Lya describes a new danger for our great cities as a result of our crowded populations and our lack of control of the industrial technologies. "Nevertheless, the Earth human must take care of himself because the heat will asphyxiate the great cities who have a large thermic surface for the accumulation of noxious gases. This also is a danger. The condensation of said gases could come in a moment. On other worlds of equal terms of civilization to yours, they remove or they neutralize all kinds of poisonous gases... " "That's it Lya, one theme aggravates another, until it seems that you want to wrap me in a halo of wisdom for intensive knowledge, as if the time was about to terminate before I know it. How difficult it is to understand all that you have invited me to meditate upon." That frequently was too much for me... . Many times I was left without absorbing the flow of her wisdom teachings. Lya was the teacher and I the smallest of her students... I also felt it hopeless to try to correspond in her discussions... I wanted to show her that I understood all that she said, but I did not want to seem false. She knew to what measure I assimilated all that she said. She could not allow falsehood and I must not fake my position. {{PAUSE=2}}
