In Tibet, before the automation of machines, everything was manual. If you had to put up a tent, it took a lot of time to do that. If you wanted to move camp, that involved a journey. Everything was very manual, all the time. If you were tired or sick, you couldn’t reach anybody by calling them up on the telephone, saying, “Save me!” You couldn’t take a taxi. Unavailability of that kind is very, very powerful. Everything had to be done manually. The manual world saves sanity.
