There's a kind of extension of the physical senses. In American Indians, for instance, the senses of hearing and smell are far more extended than ours (in dogs too!). When I was eight or ten years old, I had an Indian friend who came with Buffalo Bill in the days of the Hippodrome - that was a long time ago, I was around eight. He was so sharp that he could put his ear to the ground and tell, from the intensity of the vibrations, how far the sound of footsteps was coming from. All the children immediately said, "I'd really like to know how to do that! " And so you try.... That's how you prepare yourself. You think you're just having fun, but you are preparing yourself for later. Voilà. page 102 , Mother's Agenda , volume 3 , 27th Feb 1962
